I recently picked up a nearly identical truck and I've really liked watching what you've done with yours. I am very interested in swapping the gas tank for something larger too. Do you still have that link you mentioned that had some good info on how to go about performing the swap?
Thanks-
Sorry to just get back to you, I have gotten away from this forum for a while.
I recently had to replace the fuel pump and I modified the hanger a bit differently this time.
I used some nickel/copper alloy brake line in 5/16" and 3/8" diameters and compression fittings. Then two small pieces of aluminum angle to extend where the module bolts to the hanger ( and the sending unit grounds to).
There's a really good youtube video I came across that can explain it all better than I. he gets into modifying the float for the sending unit, I left mine stock so my gauge just reads full the first half. Its been that way for two years and hasnt bothered me yet.
To update, I have been running the truck daily for a few years now and haven't done a whole lot, just maintenance. Replaced some gaskets, deleted the AIR setup after one of the tubes cracked, added a new cat, on a set of the new style bfg ko2's now, etc.
Planning on going to 3.55's by just buying a decent rear axle and front center chunk out of a parts truck, and the truck desperately needs a respray as the 26 year old paint is literally falling off. Found a zf5 for cheap that I might pick up for "one day" but the 4 speed is great for running around.
