yes it is a 6 cylinder...my tanks get filed at the uhaul down the street. Truck lives life hard as its outdoors all the time. From what im understanding your saying it could be the LPGR freezing up. This might explain difficult starts when engine is not warmed up. then easy starts when it is warmed up as the water getting to the LPGR would be much warmer then....Im interpretting that i need to check the LPGR not for fuel pressure but to see if it has been clogged with residue from dirty water...?
So long as were not rebuilding transmissions and engines here im capable.

All in all.. It sounds like your telling me make sure my lpgr is getting the water it needs to keep from freezing up by draining it and seeing if its clogged with residue..
guess that will be my morning project.
Thanks for help guys. all suggestions are greatly appreciated.
