I grudgingly replaced the bad one with same like and kind, so far I THINK both are operating correctly. my issue is that I get "lean pops" at initial start up - for about 1-2 minutes, then it seems to run fine (no codes) my tuner thinks my FP needs to be more (currently steady around 52-55PSI). he thinks I need to replace the delcos with Whalbros and separate filter and regulator.... aarrggg. anyways very nice truck & maybe catch you out here "in the desert" soon... C10 reunion maybe!  |
Thanks! I'll keep updating this thread to get up to current times. I've been out your way for Dino's Git Down the last 2 years in Glendale. I work for AMD and we had a booth set up there, gave away a whole squarebody body in '22 and several bed kits this past year. Hoping I get to go again this year.
Your fuel pressure is definitely just a touch low, you should be at 58psi. For my setup, I'm running the Walboro in tank 255 in a stock '87 TBI sending unit. I ran hose along the driver's frame and mounted an '06 Corvette fuel filter/regulator where it's easily accessed. Then a return line goes from that back to the tank and a supply goes to the motor. That filter/regulator combo is set at 58psi for the stock Corvette. I stick with either AC Delco or Wix though, I've had issues with off brand filters and so has my tuner. Something to think about.
