How to add a larger tube or sump an OE gas tank

[Mopar to ya]

I am pulling the trigger on an E85 carb. The recommendation is 10AN fitting to the pump and 8AN from the pump to the carb. 10AN is 5/8ths. That is freaking huge! I want to use my original tank and sender. Any ideas on how to sump or add a larger tube to the tank?

I would try running the lines you have now and up-size only if you need to. 5/8th is crazy big.

What material did you fab that sump from OMM and what did youi do afterwards cause the tank is zinc plated isn't it? Spray galvanizing or what? I am going to have to do that with the fish. Nice thing about a sump is if you do it right you can incorporate some kind of water drain from the low point.

I used sheet metal from a new hood. The coating is POR15 fuel tank paint brushed on.

Did you weld in a bung? Drill a hole and use a bolt in sealed fitting? I am going to need to do this soon.

E85 uses a bunch more fuel than regular gasoline. That's why the hose sizing requirement is bigger.

Basically getting a large supply to the fuel pump and then a 1/2" line forward. So it's not that far out of whack.
