As the title says, my rear driveshaft is hitting my gas tank when my rear driver side tire is flexed a lot. What should I do about this? I've already had the gas tank modified when the leaf springs were put back there but it wasnt anything major. Here's the pics:



It left a dent in the gas tank. I can get pics if needed.

 

is there anyway to relocate teh gas tank? like put it how a bronco II has it? or a jeep cherokee? beween the frame rails tucked up below the bed floor? possibly time for a fuel cell?

 

Happens on my 3rd gen on a regular basis, rips off the zerk fitting on one of the u-joints. Relocating the gas tank is about the only option I can think of....

 

Without the rear coils, you do have room to raise the gas tank, I did this on my 1st gen:

Other folks have gone to a smaller OD driveshaft:

Downey makes an auxillary tank that fits in the location of the spare. 11 gal and 22 I think.

 

Downey resells the tanks Northwest Metal Products make (http://www.nwmp.com/). Also, they are auxiliary tanks, no level senders, no fuel pumps, just set up togravity feed the main tank. So it would take some work to make them work as a main tank, NWMP can set one up for that type of use on a custom basis. You can relocate the stock tank:

Are there any other options besides these?

If not, these custom jobs are going to be pricey right?

 

I'd just take a hammer to the tank myself...

 

That's an awesome freakin' rig!

Ever thought of running propane?

seems like there would be a way to keep the axle centered. however, i'm not too familiar with leaf springs. ....i'm more of a coil spring kind of guy.

 

You could add a panhard rod, maybe on the opposite side as the 2nd gens have it with the coil springs. But heck, if you can do that leaf spring conversion (assuming you did the work), raising the gas tank is a piece of cake, assuming you have a body lift. Or moving the tank to the rear is not that much more work from the writeup I posted. Doing either will also increase your ground clearance several inches.

 

i also have this problem with my land cruiser coils. i've tried to bend it out of the way a little, but it is very rare for me to be getting that much flex.

 

I think if you didn't have those lift blocks under there that might help the issue. Just replace the gas tank w/ a fuel cell where your spare tire goes or bank in the gas tank a tad.

 

how about this http://4x4wire.com/toyota/tech/gas_tank/

 

Hmm, it will increase my ground clearance?! I might have to do that one!!!

 

why not just dimple the gas tank to add some clearence?

 

32 gallons of fuel goodness. Eventually im going to recess it down into the floor as far as possible and replace the flex lines with hard lines.

 

How much did that run you? That is what I'd really like to do.

 

tank, lines, fittings and external fuel pump together. . . I'd say in the $500-550 range.

if i remember correctly

the tank was 300
pump was 100
lines and fittings were another 100
rest for tax, shipping, and misc screw ups till i got it right


if you go soft lined get the teflon inner liner, i can smell gas leaking through the plain rubber lines. I'm going to convert it all to hardline b/c its cheaper, safer, and wont make your car smell like gas.

 

I would think a 32 gallon tank is overkill and something around 10-14 gallons would be much easier to fit underneath, say in the spare tire carrier area, still protected and out of the way and NOT in the cab.
