gas tank idea

[Josh]

ive heard of people dragging through theyre gas tanks. especially the cheap ass NBS plastic ones... what if you got a Z71 skid plate? would that help? has anyone seen this or tried it? just a thought...

[chevyman992002]

hopefully I'll be getting a fuel cell soon, but if not, i really need to look into getting a plate under the tank.

[Will]

wouldn't a plate under the gas tank spark until u wore through it? Then when u railed, u'd just have sparks? I guess i never thought about what you drag when you rail.

see, i dunno what the Z71 skidplates are made of. i think the NBS is just composite.

[droppedgmc]

i just raised mine like IFCustoms

[Silvlowrdr]

Get rid of the tank :superhack

[01GMC]

You can cut the tank crossmembers and raise them. It will give you @ a inch of clearance. IF does the same thing. There are no other mods .. cut and lift.

[OrangeCrush]

werd to just lifting it, have you been scraping it lately or are you planning something?

nah, y2ksierra was showing me pics of his 4/8 and his gas tank about an inch from a speedbump. we were lookin on ebay and i came across some skidplates.

Yeah, thanks Josh...i'm still looking at ideas to protect my tank, i'm kinda worried about it.

[Dark Eternal]

the z71s dont have gas tank skid plates....

[Josh]

blows that idea... my 95 Z71 had one.

[grounded]

Raising your tanks going to be your best bet if your worried about it dragging on something.

[chaddurst]

I have a skid plate on mine. I would do that or raise it .

[Steve]

wow steve. I'm dissapointed. You knew how I had my setup. But I guess you don't know my email. sucks then. :nono:


:wtf: :think:

[SierraSport]

huh , it is right there by the rear tires .. But I guess it would be a good idea . I dont think mine has ever hit the ground , but I did wrench that bitch up in there when I put it back in (probably has ) ..

[Tucks20s]

I say raise it. For some reason I've never had a problem with mine dragging. I mean when I get under it I see a few scrape marks, but nothing deep or big. Mines a little lower than Y2K Sierra's when the rear is aired out and I drive with it aired out like that alot.

[01GMC]

:shrug:

To raise it .. you just need to cut the crossmembers, and raise them up as far as they can go .. @ 1-2 inches. Then re-weld the crossmember. I have been to you can wrench the straps a little tighter and you can pick the a$$ end up some more, but I haven't seen it done.

[LowBlue02]

My tank is raised, and I STILL drug a hole through it. So now I have a HUGE skidplate on it...I need to take some pics.

Can't remember who said it, but scrape marks on your tank isn't good. That's what I had at first and before I knew it, tank was no good. Watch your shit.

[thecodeman]

I had my gas tank hang on the alignment rack after my 5/8 was installed:D

[Will]

godamn, i never realized that my tank was that low to the ground... maybe i should stop rollin with the back almost all the way down...

[Steve]

godamn, i never realized that my tank was that low to the ground... maybe i should stop rollin with the back almost all the way down...

well, i am over a speedbump there...i was just glad it doesn't make contact with the bump! that is a 6" flipkit with 2" shackles installed so i cruise about as low as most people with bags do now :naughty:

[Josh]

yeah, honestly thats one of the only things i would be afraid of....

[Will]

haha most of the time i roll with my truck all the way up in the air, or at least the front. I had alot of problems with my 2/4 bottoming out, i can only image what a 4/8 is like... looks good though!

and i'm definitely seeing if i fucked up my gas tank tommorow. I pretty much every bagged truck i ever see cali crawls everywhere. I can't imagine everyone destroying there gas tanks all the time.

Were you bottoming out or having rubbing issues because of the wheels/tires you had when you had your 2/4? With my frame notched and my stiff shocks i don't have any bottoming out issues, of course i drive pretty slow around town :burnout:

[Tucks20s]

when I said scrape marks I didn't mean anything really bad, just where I drug over an area that was a tad higher than the rest of the road. They aren't that bad at all.

[chevyman992002]

i have several scrape marks on my tank, but none are very bad.

[OrangeCrush]

last nite i went to springfield College to see some friends, and the roads were so bad, i hit what must have been a ditch, cuz my whole truck just slammed onto the axle, then the bed came flying up it was insane im pretty sure it pulled the wheels off the ground on the way back up, cuz all the homies on the corner were goin nuts when it happened. to give you an idea of how hard it hit, it made the small crack in my windshield about an inch bigger.


**Back to topic** lifting the gas tank seems to be the best way..

Damm edit button.....

[Darkstar Fab]

here is what i would do.. seeing that ive had my truck bagged for about 3 years now, I've never had a problem with the gas tank you would have to drag your shit all the time to put a nice hole in it.. soo eithie raise the tank, not to hard. or get a fuel cell. lol those are you options. if you arent sitting on the gas tank i dont see why you wouldnt have a problem.. as for a metal skid plate bad idea.. maybe if you are worried abbut it getting pieced by a rock or something like that, that is what a metal skid plate is good for not protecting your gas tank when you are dragging. think aobut it if you are almost through your skid plate ( it will happen) and hey what is that gas coming out.. wait BOOOMMMMMMMMMMMMMMMM... lol yeah what you want is a plastic cover i had one on my 98 so im sure you can get one somewhere........... like i said its not that big of a deal.. but if your truckis sitting on the gas tank when it is laid out.. i would sure do something about it... good luck guys

[Silvlowrdr]

When u guys lay your truck out, isn't your gas tank the lowest thing in the back of your truck. Haven't laid my truck layed out yet, cuz i'm still in the process of installing my four link, but when i dropped it with a jack the tank hit first. I think that would bother me layin frame. Anyone feel the same??? :think:
I'm throwin a fuel cell in anyways cuz i had to remove my tank for the four link. Anyone out there with a cell... and where'd u put it??? Behind the axle or in the bed. :help:

[thecodeman]

On the new body style trucks the gas tank and transmission crossmember are the lowest points.

[Silvlowrdr]

Haven't messed with the front yet, so i still got a virgin xmember. Gonna christen er soon though. :cheers:

[Josh]

this is true for the 01 and newer trucks. the 99s and 00s had a smaller tranny Xmember.

[thecodeman]

Ah. Did not know a difference in the years.

[bcubed]

I have a 2000 and my brother a 2001 and the crossmembers are the same, I've heard the '99 was different, but can't confirm it.

Bill

[an032nv]

when mine was bagged they lifted the tank and put a plate under it in case it ever hits, although I don't drag so no worries :D

[chevyman992002]

i have a '99 and my tranny crossmember is flat. i lay on the frame up front and lay hard on the gas tank in the back. but im gonna get rid of it and get a fuel cell just to be on the safe side.

I have a 99 too. My crossmember is flat. I don't really want(or need) a new gas tank or cell, but is there any way to modify the stock tank to make it maybe sit up higher?


I am going to drop it 5/8" and I was pondering the idea of making a full length skid plate since I got a welder handy. I am planning for alot of scrapage :naughty:

If you have a welder .. then just cut the gas tank crossmember(s) and raise them up, and re-weld. That is all you have to do .. will get you a little over an inch, and is above the frame.

[braden1498]

When I got mine bagged, I had a new fuel cell put in that way I would not have to worry about this problem. I put in a triangle engineering fuel cell because you can use your stock sending unit. It cost about $250.00 that was with shipping too.

[Loki]

i don't think i would weld anything 5/8" to these new body style frames...they are soo soft bro...even if you hit it on top and bottom, it wouldn't be sturdy IMO...to give you an example of how strong it is, i took a couple of pair of vice grips on a small piece of the frame i cut out, and me and phshy1 bent it with no problem...3/16" should be fine for that, but just to let you know...stay flush with the frame and raise the tank...

What cell did you use, where did you put it, did you modify the locations at all, and how many gallons is it?


I would like one, but damm 16 gallons is too small.

[chevyman992002]

hopefully sometime in Feb. i'll be getting a cell frum summitt. I'm getting a 20 gal. and putting it in the center of my bed right up against the cab.

[braden1498]

Triangle Engineering is the only manufacturer that I could find that my factory sending unit would bolt up to and my fuel gauge still works. I got mine in 20 gal., the only thing is you will have to reset your fuel gauge. About where mounting it, I put mine where the spare tire was at, temporary cutting a hole in the bed floor until I relocate it in the tailgate. All you have to do is fabricate mounts and extend your fuel lines. Also I called Triangle and had my tank modified with no vents.

You have a number or website for those guys? Wouldn't mind calling them.

I meant that I was going to drop my truck with a 5-8" suspension drop.... and then i would make a skid plate out of steel. Most likely 1/4 at MOST. I know, the new frames are very thin and light in my opinion.

How come u got the tank with no vents?

[braden1498]

How come u got the tank with no vents?


It comes with like 2 vent line fittings, since mine had to be made(backorder) I just got it without the fittings.

yeah you can say that again...thin, light, weak, cheap....what can i say....hydroformed frames suck ass.

[02chevy]

put the tank in the bed,worked for me, no more problems:devilfing

[Silvlowrdr]

What kind of lines did u guys use when u put your cells in the bed. The fittings and braided lines are expensive as shit. I just baught a RCI cell for 200 with a GM sending unit in it and a holly external fuel pump. Finding that local stores double prices on shit, so i have to wait a week to get shit offline, but its half the cost with shipping. Pain in the ass. Didn't know if any of u guys went with rubber lines. Some people say they'll collapse. Never messed with this shit before.

[02chevy]

my damn pic is so big i dont know how to get the shit smaller,i suck at this computer stuff
