How To Change The Fuel Pump In A 1991 Suburban

Today I'm changing the fuel pump in my lifted 1991 chevy suburban 2500! Its a bit easier than a normal truck because its lifted off the ground so high, which gives the ability to sit upright under it.

First thing i did when i bought my 91 suburban 20 years ago to use on many trips, was to take up the rear carpet and put me a trap door right above the fuel pump. Also carried a pump with me.

Man I have a 88 fuel pump just died today looks like il be doing the same! Mine is also a 2500 with a 6" with 37s

What all did you have to do to do a 6” mine has a 4 right now I wanna go with a 6”

Just food for thought. Clearly you won’t be changing fuel pumps all to often on it (We both Hope) but for lots of things on a beast like that, get yourself a motorcycle jack for about $80. That and a sheet of plywood make lots of virtual overhead tasks easier.
I was happy to have one when changing mine in my Expedition not once but twice...

Agreed. I use a harbor freight transmission jack. Cheap and flat and works perfect.

What size gas tank is that? 31 or 40?

When you did the fuel pump did you change the lines up to the engine?? if so how hard was it?
