8 AN fuel pick up w/ 6 AN return for stock tank?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Im converting my 6.0L LS swap from a carb over to a Holley Terminator EFI set up. Im going to run and external Holley pump but am having a hard time finding an 8-AN feed/6-AN return that will fit the stock tank in my '72 C20 Suburban....any help/input would be greatly appreciated. Thanks!!

which part are you looking for? The AN sizes are the 1/2 and 3/8's respectively. You can adapt to and from an existing hardline with a hardline (tube) to AN adapter fitting.

yea, the problem is that the factory hard lines coming out of the factory pick up are much smaller. Im looking for an aftermarket pick up that actually has an 8-AN pick up and 6-AN return, all the way down to the tank.....Mallory used to sell one but nobody carries it anymore.....

If I can't get anything to work, I may consider a replacement sump style tank with bungs in the sump for an 8-AN pressure line and 6-AN return....although Id rather not spend the money if I can avoid it.

From sending unit to pump on mine I just used reg 3/8" gas hose, after the pump is where I started with my -an fittings and steel braid hose. I used the vette filter reg and just hooked the bypass back to the tank with 5/16" gas hose.all my stuff is under the bed and outta sight so visually nobody sees it .really not much need for steel braid on suction side of pump. And I've had no issues on the return either
