Subject truck is a 98 12-Valver.

My truck loses prime after sitting overnight and has a small puddle of fuel accumulated under the engine. Usually about 10-15cc or so.

Upon underhood inspection I discovered (2) parts that are disconnected. I don't know what they are and what they do.

I have yet to find the source of the fuel leak.

Can someone tell me what these parts are and what they do ??

See pics below.....

1st is obviously an electrical connector. The connector appears to be melted and not connected for sometime. Is this the fuel pump that it connects to ??




Next is a vacuum line that is located near the firewall right behind the fuel filter.











I did notice a small puddle of fuel behind the fuel pump in a valley on the engine block.

 

Anyone know of fuel system schematics/pics (wiring and fuel lines) for my truck ? (98 12 Valver).

I'd check around the lift pump/pre-filter real good.

 

I believe this a connector to the fuel pre-heater then correct ??

 

Anybody ??

 

When my 95 did that very thing, I found the return line leaking. It was at the rear of the head, drivers side. There was a small crack in the steel line. I slid the hose up a little farther and it was ok.

 

replace all the rubber lines and I bet your problem goes away. those lines are prone to leaking.
