I recently purchased a '94 12V with about 200k miles- it ran great up until last week. I went to start it and it had a rough idle, drove it down the street and it was puking white smoke, popping and had no power. Got it back and realized a copper line (that i think goes to the fuel pressure gauge) had snapped and was dumping fuel. I plugged it, put new filters on (has fass system). Now i have fuel up to my injection pump but not going to past that. Has anyone else had an issue with this that can shed a little light before I throw a $1,200 part at it? Relay is good and the solenoid seems to be functional.
