Thread: Plumbing fuel line

Tweet

sorry to argue but the Holley Red pump doesn't use a regulator, your thinking of the Blue pump.

I agree about the hard line, just use a small piece of rubber each end to cope with movement.

I've always mounted the filters after the pump, they can handle particles and i've never had a problem.

I've also switched these days to Carter pumps as they are quieter.

2) You didn't mention a regulator, you need one. Mount it near the carb.

3) Why all of the rubber hose? Stainless hose is still just "covered" rubber hose and will need replacing from time to time due to age and attack from the gas chemicals. IMO, you would be better off using hard tube. You can make it nice with stainless 3/8" tubing and AN tubing sleeves and tube nuts. It even polishes up nice on the buffer before you bend it. It will last and be cheaper than buying the AN fittings and stainless hose. But......you do need to borrow a quality (Imperial) tubing bender and a AN 37 degree flare tool if you go this route. You only need a hose that flexes between the engine and the frame, about 12".

4) One thing that I always do, is install a fuel shut off valve at the tank. The valve can shut off the fuel flow when you service the fuel filter or need to work on the fuel pump. Any good hardware store sells "ball valves" for natural gas that work fine with gasoline. They flow better than Earl's and only cost about $10. Time and money well spent.
