Engine Performance problem
1985 Ford E-Series Van V8 Two Wheel Drive Automatic 140000 miles
Was driving on the freeway last night and the van cut out badly as if it was running out of fuel. I have two fuel tanks. Fuel switch under dash powers the electric fuel pumps inside each tank. I can hear them when I flip the switch so I assume the are working. In fact, I unplugged one of the fuel lines and turned ignition key on and yes, fuel shot out of that line like a water hose. So I know fuel is getting to the filter. It's the filter I think might be clogged, or I have another major issue. The filter is a small metalic one about 5-6 inches long. It has TWO connections, obviously one from each tank. Hard to get off with a wrench. I tried and could not loosen it. Had to abandon vehicle on side of frontage road to major freeway. Going back this morning to change it out with proper tools. A crescent wrench doesn't cut it.
Both tanks are full. When I switch to rear tank, engine dies. I notice the connection from the rear tank goes to the top of the filter, and the connection from the front tank goes to the very front of the filter. Have not been able to check the flow from the rear tank yet, but when I take the line off I'll check today.
If there is flow out of both fuel lines, shall I assume the filter is severely clogged? What else could do this?
If I start the engine, it will idle horribly on the front tank now and die after a minute or so when switched to the rear tank. If I give it any gas, it dies.
It must be getting some gas to stay running (even if horribly) on the front tank.
The carb is new, a two barrel looks to me. It has a new distributor, belts, hoses, all looks good. It was running perfect. No smoke, clean oil dip stick, tranny good. I drove it for two weeks no problems and now this. Please help, I'm stranded.
have the same problem?
