Hi,
I am brand new to the ford forum, and looking for some advise. Last year i bought a sweet 1970 F250 2 wheel drive survivor.I want to use it as a daily driver, so fuel economy with the stock 360 and carburetor was an issue.Talked to alot of people about it, and ended up searching for an efi donor vehicle. finally found a 1990 Lincoln, and last weekend put the 5.0 HO efi with tranny, into the truck. Slowly working on wiring, transmission linkage, etc..
not sure what to do about the fuel pump. should a guy mount a new fuel pump on the frame? do i need to run a return line? should I look for a fuel tank out of a 1990 efi 5.0 truck that has the propper pump? any suggestions ?

 

I hope you also got the ECM and all the related wiring. You took a big bite with this project and you will be busy quite a while trying to get the project installed correctly.
It would be a good idea to read up on EFI systems so you don't overlook any requirements since there will be many.
You should have a EFI fuel pump with a provision for a return line from the fuel pressure regulator. Then you have the relays for the ECM and fuel pump to install.
There is also an inertia switch to consider should you ever get into a mishap it will shut down the fuel pump should the engine still be running to prevent a fire.

 

Yes I still have the car with all of the wiring in tact so everything should be there that I need to rob off of it. also bought a wiring kit (fuse panel, relays, etc.) that is supposed to go from the Ranger truck electrical to the cars computer and motor. Between the two I should have everything. just need to get going on it! I think I will go with the frame mount fuel pump and keep the factory truck fuel tanks. Just trying to keep it as straight forward as possible. Where should the inertia switch be installed?
Thanks for any input.

 

You probably could use the inertia switch from the car. Keep in mind the wiring from the auto can also be used on the truck. Some Fords had the switch mounted on the upper RS kick panel, some had it mounted over the trans hump inside the vehicle and the cars generally had them mounted in the trunk , close to the pump. It should be kept inside the vehicle to protect it from getting accidentally tripped. You can check it's operation by just rapping it with your hand and you will hear the ball roll off the spot. Just pushing down the button will reset it.
