Ok, just to get this out of the way - I know the MAF 38 gal (from Australian Long Range Automotive) hangs below the frame and sits close to the drive shaft. I'm ok with that because I want the added half tank of range (specifically, in the tank), and don't crawl a lot of rocks.
So I've just "finished" with the install, and boy was it more hassle than I expected. That's what I get for not owning a lift. Regardless, the tank is in, the straps look to be well fitted to the tank's contours (not sure if they're adequately tightened though), and my modified-to-spec fuel pump assembly is installed and working correctly. The rear hoses are connected and clamped. All the top side connections are in place. The drain has a proper M12xsomething plug in it and no leaking.
There was about an inch of space between the rear of the tank and the drive shaft, just ahead of the U joint. I added 10 gal of fuel to the tank and checked for leaks, and so far so good, BUT as soon as I started to roll out of my driveway I began to hear a loud grinding thumping sound. Rolled back into the driveway, and looked to see what the heck, and beheld the rear side corner of the tank pressed right against the driveshaft and both getting and leaving a nice rub.
I realize 10 gal is something north of 75 lbs, but I wasn't expecting the tank to shift so much that it would scoot over and hit the DS. thinking on it a bit harder, I realized that looking down through the service port under the second row seats, the tank was sitting and inch or so further back than factory. I also have the e-brake cable passing over the top of the tank in a couple spots (rear corner, front portion).
Any ideas what I screwed up? I was pretty sure I tightened the straps in thoroughly - though the rear hanger on the frame side does have some gap between the hanger bracket and the new tank's strap; I wasn't sure if that's a problem.
My thinking for tomorrow is to stick a jack back under the tank and see if I can raise it at all. If I can, then tighten the rear frame-side strap mount and see if that pulls the tank further from the DS. Second option will be to loosen the hose clamps on the hoses coming from the back of the tank, loosen the straps a bit, and try to shove the tank forward without going so far that the rear hoses can't be adequately secured. Third option is see if the e-brake cable is keeping the tank from being fully raised, and pull the cable out from on top of the tank (loosen straps, detach the rear of the cable, pull it over the top, and then route it past the tank straps - I don't want to drop the tank unless strictly necessary).
Any and all suggestions welcome!
