Jump-start a fuel system?

There's a gigantic barge (okay, an 88 Crown Vic) on craigslist, way the hell over on the other side of the city. Was $300 a week ago, now says first $200 takes it, "needs fuel pump".

If I still lived over there, I'd probably grab it for a DD so I can take the Bird apart to fix things it really needs done (and I'd still have somewhere to put it to work on it, which I don't where I am now). :(

However, without a fuel pump there's no way to check the engine, transmission, rear end, brakes.... pretty much everything, and there's no way I'd have it towed all the way here just to change the pump and find the engine's blown. I just don't have the time or patience to deal with that kind of . :nono:

It got me thinking :eek: that it might be feasible (for this or other injected Fords) to get a length of high-pressure hose, fit a schrader valve to each end, and connect the fuel rails of each car together, like a double-ended pressure gauge, minus the gauge. Start up the bird, or jump the test plug so the pump runs, which should pressurize the other car's fuel rail to get it running. :banana:

Any thoughts, first-hand experience, fuel-flow specs, patent-infringement concerns, mental-health concerns, etc, etc,.... :hick:

That doesn't sound like to bad of an idea. The only problem I forsee it that you would be filling the other cars tank.  I think the best way would be to disconect the fuel lines on the good car and run them over to the other car. Then you you would be returning the extra fuel to your tank. Also then you know you have the flow needed to make it run right. Don't think you would have enough pressure going thru the Schrader valve

I think you have to be a little crazy to come up with good ideas. :)
 
Sounds like a good idea though. I think I'd jump the test plug rather that running the engine on the fuel donor car.
 
It would be a nice tool to have in your bag of tricks when you go to look at the car. But before I hooked it up, I'd try the old bump the fuel tank while cranking the engine trick to see if the pump is just stuck.

Sounds like it should work. If the FP check valve and the regulator are ok you should be able to pressurize the Crown Vic.

Cool idea, thats basically how the professional fuel injector cleaners work.

To keep from pumping your gas into the other tank, you can run your engine with the vac line on the regulator, which will set the F/P to approx 30-32 psi(or use the jumper and pull a vac with a hand pump). The other car with the vac disconnected from the regulator won't bypass back to its tank as it's regulator will be set at 39 psi...

Did you get a chance to try it out?

Nah, by the time I got around to asking about it, it was long gone.
