Sealing a return line fitting, through a hole in the top of the fuel pump basket?
 

I have for all the track rats that have installed surge tanks for heavy duty track use to prevent starvation (and are using the factory main tank): How have you guys run the fuel flow from the surge tank, back into the main fuel tank? Specifically, what configuration of fittings, washers, and location did you use to breach the factory fuel tank? How did you achieve a fuel tight seal?


I have seen some pictures on here of a setup by someone named Visconti, but they are banned, and I cant message them. It looked like a 90 degree AN fitting that had been drilled through the top of the fuel pump basket. This seems like a good, simple location that can be done easily, but how would i seal it fuel tight against E85?

I used an Npt to 8an 90 with a nylon washer on both sides, with an Npt nut on the underside. Never had an issue.

90* bulkhead fitting is what you should be looking for.
