Help with Replacing LIFT PUMP

The dealership tells me my issue is my lift pump. They want 680 total for the pump and install. I ordered one from advanced auto for 179 and Im going to do it myself. I know where it is located, on the frame rail under the drivers seat. Besides the fuel line tool, do I need anything else to remove it and install a new one? How exactly do I do it? Do I need to buy more fuel line or anything? thanks in advance

Assuming it's the proper part, all you need to do is disconnect fuel lines and power connector, unbolt the old one from the frame, bolt the new one in place, and reconnect fuel line connectors and power connector.

The factory replacement FUEL pump is way easy to change as it pretty much just bolts and plugs in.

I would not say the same for an aftermarket one as you probably are required to reuse the mounting bracket, some fuel lines and the wiring harness. In either case you will need a fuel line disconnect tool, not sure what size so you might want to just buy the set. Not too pricey and yes the cheapy auto parts store ones work just fine. if the truck is real dirty under there it might be good to pressure wash the area around the old pump first.

Dont. That pump is JUNK. Mine lasted 300 miles. The problem is that its a modified gasoline pump, and diesel has a different electrical resistance than gasoline (yes, the commutator brushes run bathed in fuel in most fuel pumps. I dropped my teeth when I discovered that - seems like we'd see these things bursting into flames on every corner...)

Spend the bucks and get the higher-priced Bosch pump available from AA, which is a direct OE replacement (the original pump was made by Bosch). Its also easier to install than the lower-priced hack job.

I am about to tackle the same project and I am wondering what the fuel line disconnect tool is and where I can get it?

Also, should I expect fuel to come gushing out when I disconnect the lines?
BTW, I'm doing it on an IDI... is the pump going to be in the same place as the PSD was?

Thanks so much!

You may want to post this down in the IDI forums. The 99+'s and the IDI engines are two different animals.

Just did this on Mama's Ex, and at first I bought a aftermarket.
When I pulled the old, and compaired it to the replacement I boxed it back up, returned it and sucked it up for the Ford unit. There just wasn't any polishing that turd.
T'was the right choice for me, your mileage may vary.
