Fuel line check valve...

[jtdesigns]

Just wondering if our trucks have any sort of check valve in the output side of the fuel system. If not I think I'll rig one in mine just to see if it changes anything.. Not that I have a problem, just for,,, we'll say scientific research.

Only check valve in the system is the check on the fuel pump for supply, the fuel regulator, I guest could be a "type" of check valve, nothing in the return lines, But........the vent lines are a check valve style that trip-in, in case of a roll over.

 

I get where your going with this........keep the fuel rail pressurized at full, for easier starting???? :hmm:

The fuel pressure regulator on the front end of the rail is exactly that. It regulates the fuel pressure by letting fuel out of the rail as needed and is a one way valve...or check valve if you will ;)

Cool... Didnt know that! I was thinking of splicing one right before the fuel filter.

Thanks guys!
