Got a Tanks tank with in-tank pump which have female 3/8" NPT fittings for supply and return. I want to from the 3/8" NPT to regular GM quick disconnect and run nylon lines but I can't fine the proper fittings to make the transition. What fittings do I need and where can I find them?
Also, modern nylon fittings require a special tool to press on. The barb dimensions are very specific, you likely won't find them direct to an old NPT port. AN fittings are easily adaptable to GM quick connect fittings and readily available though
On my 1992 swap i used plastic lines from the tank to the fuel rail. I used the the 3/8 and 5/16 adapters (brass 3/8 NPT to plastic) KO95 and KO100 from the this kit in the picture to adapt to fuel line coming out of the tank. The kit is S.U.R.R KP1200 kit.
