2000 gmc jimmy

hello all, I am about to replace the fuel pump in a 2000 jimmy for a friend. The price of this unit was a surprise! To see all of the sending unit was plastic was a surprise!

Will I be surprise again when I drop the tank ?

Or should it be smooth sailing ???

before you drop the tank, look in the rear of the jimmy for a access panel, a lot of gm vehicles have one over the tank for access to the fuel pump without pulling the tank. if there it is a very easy job to switch out, also check the ground to the pump/tank and clean all connections.

there's no access plate on the vehicle.
YOu'll have to drop the tank, and might find fuel line connections a surprise.

thanks bigguy I did drop the tank and yes the fuel lines were a surprise, What the heck is going on with todays vehicles? Gone are the days of steel lines and threaded fittings.
There was two electrical plugs one to operate the pump the other I broke off the sending unit. Does any one know what that is for? Damn PLASTIC!!! but it is still pumping the fuel, should I be concerned?

it is probably to operate the fuel guage. only if you want a working fuel guage.

No speedwrench I have a fully functional gas gauge. on the otherside where the wire plugs into it looked like a rubber valve of some sort.

The other connector could be for a pressure sensor so the OBDII can check to make sure you put the gas cap back on right. Do you have a check engine/service engine soon light on?

Fuel Pump changed!!!!!!

I changed the fuel pump and boy were you right about the connectors. I had to replace one. It took me 6 hours with a few Union breaks in there and 3 trips to Auto Zone. I love those guy. $320.00 later it's running. Now to the trans. cooler lines that are leaking all over my pass side brakes. Then the brake pades all the way around. No man to fix it so I get to do it my self. Thank you for the insite on the fuel pump issue.
