Re: Huck's 85 GMC shorty
huck, enjoyed the build & looking at a nice truck!! I too have had a few "dealings" with the AC D pumps (EP 381) I installed 2 in my '86 LS SWAPPED truck (build on here) and one failed after about 3 startups. 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!
