Anyone ever converted their 4 door Tahoe fuel system with the side tank to a 2 door rear tank?
I have a 99 4 door. The fuel tank is rusted beyond repair. Yes, I know it's plastic. The embedded steel ring around the sending unit hole has rusted and distorted the hole so it will not seal. Of course the retaining rings are rusted off. I used a new fuel pump module and used permatex no 2 sealer and stainless steel sheetmetal screws with fender washers to retain it. That worked for about a month and now it has a small leak again when the tank is filled.
I cannot find a new tank anywhere. A few months ago I saw one that was $600 or so. Now I can't even find that and that is a little steep.
What I can find at a reasonable cost is a 2 door Tahoe tank. I did some research, apparently they put the spare tire up inside the cargo area, and put the tank underneath. I went to the junkyard and did some research there, they used a bracket to hold the spare on the driver's side. I still haven't test fit my spare up there to see if it would fit in a 4dr.
I would have to buy another new fuel pump module, the 2dr tank takes a different one. I would have to extend the fuel and vapor lines and the wiring. Looking at it, I think the filler tube and the large vent tube may work, it looks like they are pointing in the right direction.
Has anyone done this before? Any other options? As many of these things that are still on the road, it's hard for me to believe the aftermarket has not stepped up with a new tank. I am afraid to get a used tank, it will eventually have the same problem that mine has I am thinking.
P.S. I also see the Suburban uses a rear mounted tank. I am assuming since it's larger and the Suburban is larger that it would not fit under the rearend of a Tahoe.
