Ok, I'm using a 3/8 solid fuel line and I'm making a fuel cell to go with it. I need to know what size AN fitting I'd need to use from the bulkhead to the fuel line. Any help is appreciated

3/8 equals -6 AN line Easy way to figure is that AN lines are sized in 16ths of an inch. -6 line is 6/16ths = 3/8

But I have never seen-5 an to match 5/16 line. Seems odd to me.

I also have another question but I don't want to start another thread to ask it. How easy is it to convert from TBI to a carburetor? Will an older style intake fit the TBI heads?

Small block chevy?

If so, standard intake will fit, but you will have to elongate the two central holes on both sides. And change distributor.

Alright. I initially thought the intake was the same as a Vortec but that's way easier

Vortic are all vertical. Tbi only the center two on each side are.

Maked it a royal pain in the ass to build a tbi vortec on the cheap. Fricking $300 intake.

I'm lucky if I'll have $300 in the entire engine
