[QUOTE="SoCalHarley, post: 16847730, member: 23251"] I do not recall seeing anything like the item circled in the picture when I did the new DeatschWerks 340lph pump recently. From what I have researched the DW pump has an internal check valve. I had a Walbro 255 in the car previously and it worked but I thought the pump might be the issue so that's why I replaced it, plus it was 25 years old and on the edge for the applicaion. I also replaced the Aeromotive fuel pressure regulator thinking that might be the cause but no luck. I have also checked the FRPS to see if there was any fuel leaking into it and that is dry. There is no issue with fuel pressure when the car is running. Again if I let the pump prime for 5 sec the car will start right up. It never did this before so something is causing the pressure to drop when shut off. [/QUOTE]
