Where to get sending unit flange?
Surge tank is going to fix the issue with the short flat gas tank that an FJ55 has stock.
What I'd like to do is make a surge tank that can use the stock GM sending unit/fuel pump unit.
So, the question is where can I get a sending unit flange?
I'd rather not buy/butcher a new tank to get it.
I want to use a stock Chevy fuel pump into the surge tank. Thus, I think the "easy" way is to use a stock sending/fuel pump unit and the associated flange.
Unfortunately, so far, I have not seen a source for the flange on the tank.
