Did a search and came up empty. I have a 380 that has been sitting for a couple of years and does not want to stay running. At first it would run for a few miles then start sputering and very hard to keep it running.
What i have done.
pulled tank and cleaned
install new strainer in bottom of tank
fuel pump replaced by previous owner I can hear it running and did a pressure test of 100psi
replaced fuel filter. Alot of rust came out.

After doing these things it starts rough and idles then the pump starts moaning and it starts to die.

I know that 100 is too high so I am thinking the return line may be clogged. I dont know which line is the fuel line. POS Haynes manual is very vague.

Also the plugs are white like they are not gettin enough fuel.
Just did. Hard to read and cannot tell by picture which line it is. Any suggestions?
Yes, thank you I thought I was going crazy. How would I clear that line?
when you say after the cooler I am lost. I cannot follow it back from rear and cannot find it in the front passed the cooler. Any photos or suggestions?
I pulled the other line off the ac and fuel cooler line and blew it out back to the tank. Put it back together and it runs like a charm. This has been an ongoing repair for 3 months. Thank you all!!!
I agree Rowdie, Its almost as nice as your Avatar.!!
