Just get a Walbro GS340. 255lph rated fuel pump.

 

Is the Walbro an in tank pump? Is it a plug and play?

 

It's an intank and pretty much plug and play. You may have to splice in the wires.

 

Thanks for the info!

 

I put a Walbro GSS342 I think it was ( it was for the return-less fuel system, but they said it would work fine for my 01). WAY cheaper then what he just paid. I think around $140-50 for everything and its a 255 lph pump. I got it from Livernoris Motorsports. I did find it cheaper from another place online, but I already had this one. Had to splice a couple of wires, and replace the hose from the pump to the top of the tank, but it wasn't too bad of a deal. It doesn't seal to the bottom of the tank as well as the stock pump, but I have ran it down till the fuel light comes on and then some, and it has never stuttered or ran lean.

Oh and I used my chery picker and some straps to pull my bed for the install. Did the whole think by my self in under an hour.

 

i need to do something like yesterday. should i just get a replacement pump from the dealership?

 

I'd get a Walbro pump and install parts from here, MUCH cheaper and pumps more fuel.

 

The only problem I had when getting a fuel pump was finding out what kind of pump I had in my truck, either a TCF or a TCU. I just guessed and when we pulled the bad one out it said TCF on the top of it. Hope you get that Denali all fixed up!

 

truck bed is off. Should have my Walbro GSS340 with install kit tomorrow. Hope it is as easy as everyone says. I'm a little worried.

 

I got the STS supplied pump (I think it is the GSS5342), I cant run mine under a 1/4 with out it leaning out. I have also droped the tank and pulled the bed on this same truck. I will NEVER drop another tank again, pulling the bed is WAY too easy IMHO
Here is a LINK (for some unknown reason) lol
