Can you use hydraulic hose for fuel line?

hydraulic hose will work fine to. It won’t deteriorate. The only down fall is its big thick and harder to move around then fuel line. I used fuel line rated for 200psi and those special barb fittings.

Why does my fuel pump run at 43 psi?

With Ignition ON, fuel pump runs for @ 5 seconds at 43 PSI and then shut down automatically. This will allow fuel pressure to build in the line minimizing hard starting problem. You are correct in your search, Scotty. Loss of fuel pressure may be due to faulty check valve (in pump assembly) or Fuel Pressure Regulator-Fuel Injector.

What should the fuel pressure be at idle?

Fuel pressure gauge indicates that the fuel pump is providing 35psi at idle and throtlling up gives it another 6psi or so. With the ignition off the fuel pressure immediately slowly drops and after a couple of hours it’s down to about 15psi.

What to do when your fuel pressure goes down?

To check if the problem is with the check valve, pinch the line downstream of the fuel pressure gauge (between fuel filter and fuel rail). If the pressure goes down immediately after pump shuts down, problem with check valve.
