HP500EFI fuel pressure attachment point
 

Can anyone tell me where is the easiest and correct point to take a fuel pressure reading on that engine. I am looking for the place to plumb in a "tee", for the line to the guage, thanks.

There's probably better places but I've had a small high pressure hoses made and installed where the schrader valve is on the fuel rail. I connected a sender to the end of the hose for an electrical gage but this would also work for a mechanical type also.

I took the shrader valve out of it and just put a # 4 hose on where I conected my gage for testing , then just put a cap on it.

THANKS GUYS Just went on a site showing the fuel rail breakdown. The schrader vale looks a good place to tap into. There is also a pipe plug on the far end of the rail on the bottom where the regulator mounts that may be an option. What ever is easier to access is where I'll tap into.
