fuel pump preasure

I tested my gauges, and they are good. this is how i made the connection.
1. removed fuel line exiting the fuel filter.
2. attached gauge to the fuel filter.
3. turned on pump
4.gauge reads greater than 100 psi
5. this is the only reference I could find

Walbro Part Number: GCL606
Minimum Current: 12 Volts
Operating Pressure: 58 PSI
Minimum Flow @ Outlet: 38 GPH High Pressure
Fuel Pump Location: In-Line

6. the reason i began investigating in this manner, because i blew fuel pump relay. and i wanted to see if this was a indication of a bad fuel filter or pump.
but both appear to be good. new relays will be here tomorrow.

this would probably be fuel pump spec's. and with zero flow, which was how i measured the psi. it is over 100 psi. but at 60 psi you have established the required flow rate. I believe, I am a chemical engineer not a porsche mechanic, but learning now for 15 yrs.

On the passenger side fuel rail there is a spot to check fuel pressure while the car is running.

This is the normal spot to check pressure so that you can see if the FPR (Fuel pressure regulator) is working right.



I removed my cats so that the exhaust flows better and I ported the heads and I run 56psi. 50 is lots for a stock engine and more is not better in every case.

I hope this helps but it was more then likely just an old relay.
Most on here replace all the relays and fuses just to be safe.

Come on James, loosen up those purse strings and send the $28 big ones

If you want the privilege that is.

where do i send it, must have missed that when i registered.
