Question: I am running a Holley red electric fuel pump mounted to my 1934 frame with a rubber pad between the pump and the frame. Is it best practice to run hard line into and out of the fuel pump or should I put on hose barbs and run rubber line? Or does it not matter? Thanks in advance - Bantam
One of the Holley pumps makes a bit of noise but I can't remember witch one, red, blue or black. I've always hard lined electric fuel pumps but on a street/strip car noise is not an issue. If I did hardline I'd be tempted to isolate the line on both sides of the pump with rubber under the line clamps. Be sure to install a filter before the pump.
Stainless braided hose with AN fittings on either side of the pump.... They all make a racket, red, blue, and black.
They're easier to change if there is a flexible line in there someplace. And you will change them, oh yes...you will.
Hose in and out. No need to try to isolate the pump housing when it's a hard mechanical connection with tube.
Hose barbs and short section of rubber hose both ways. Isolates vibration and makes service/replacement easier.
I would do two short pieces of rubber into the pump If you don’t want to do rubber line/ barns and clamps. You can do AN fittings like squirrel suggested. Or go ta an hydraulic hose place and get two short hoses with fittings on the end. Just specify it will be used for fuel so they supply the correct hose. At the very least 1 side should be rubber to make RE&RE easier . Also a fuel filter before and a tank shut off valve are good ideas .
Thanks for all of the feedback, guys. As always, much appreciated that you take the time to share your experience. Bantam
I use fuel injection rubber hose on either side of the fuel pump, ethanol in the gas doesn't eat them up.
