Fuel pump question.

[CWELDY]

Fuel pump on my 99 sport is dying. Looking online, there are pumps for Mexico built and USA/Canada built Explorers. Is there really a difference? Mexico built are cheaper.

 

[bluestream1]

you want the Canada/USA

With something as critical as a fuel pump I would stay away from Mexico when possible.

Don't think it means the pumps for Explorers built in Mexico are made in Mexico. I'm curious as to what the difference is, too.

 

[RandomNerd2000]

Maybe the difference is, the ones that sucked were made in Mexico, and the good ones were made in USA, just kidding, haven't got a clue as to what the difference is.

The Mexican build model will use a different fuel pump. Use the USA/Canada pump

I've installed 6 Bosch fuel pumps (in 6 different Explorers/Mountaineers) in past 18 months. Can't beat'em at around $50-$60 on eBay. All work great. They come with everything needed (except the strainer and new fuel filter). You can spend a lot more. It's your money.

Whatever you do, don't buy an Airtex fuel pump.

I'd say that's good experience. Hopefully koda2000 will be chiming in. Stand by.

No need for me to chime in. swhawaii has said it all for me.

Is there a check valve in the pump to prevent drain back or is it in the assembly somewhere? I have to cycle the key a few times for it to start quickly.

The best way to check your fuel pressure is by using a fuel pressure gauge. You can borrow one from most auto parts stores with a deposit, or buy one from Harbor Freight. If the '99 has a return-less fuel system, you should see around 65 PSI of pressure at the fuel rail and the pressure should hold for a couple of hours.

I believe the '99 had the return-less fuel system with the fuel pressure regulator in the fuel tank (like the 2000/2001). There is also a short length of hose between the fuel pump and the FPR and the FPR and the fuel line. These pieces of hose can sometimes split and/or leak. This can cause you to loose residual pressure to the fuel injectors. The FPR's rarely fail (unless they physically come apart). The Bosch fuel pumps I use come with enough fuel line to replace both pieces of submersible fuel hose in the tank.

In any event, if I was dropping the fuel tank, I'd replace the pump.

Have a part number for the pump?

Have a part number for the pump?

I would call Bosch Automotive Tech Support's 800 number and ask (I don't own a '99). Tell them you want a kit with the fuel line, FI clamps and jumper wire for your vehicle. Once you have the part number look on eBay or Amazon for the best price/shipping. Don't forget that you'll also need to get a new strainer sock and fuel filter. These parts don't come with the pump, as one pump fits multiple vehicles.

I found this number for Bosch Automotive Tech Support 888 715 3616
