Well, I got the pump installed. On my back for four hours in the freezing rain and slush. It was pretty miserable. I'm lucky I had the help of a mechanic friend.
While doing this job I realized that the 2-door Blazer has a reinforcing beam on the underside of the bed that traverses right over the top of the pump. So I don't think cutting the floor would be the best idea on this particular vehicle. Not if you want a significantly weaker bed floor. But the rear mounted tank is easy enough to lower and the pump is easy enough to get at. We used two jack stands at the rear of the frame rails for a little extra room to move. I saved about $500 in labor, so that must be worth terrible work conditions.

 

4 doors have that as well.. if you look in my photos, just cut it. and the best floor is not weaker.

 

i do alot of fuel pumps at work on the lift with tools. i couldnt imagine doing this crap on your back in the driveway. though i have dropped tanks on old k5 blazers, but they had no pressure hoses you just cut them and replaces them so you dont really have to disconnect anything.

when my 93 s10's goes out ill be hacking the floor... since its just a offroad truck ill probably just make a hinge set up encase i have to access it on the trail for anything

 

I have a 1995 S10 Blazer 4X4 4 door and would like to know if anybody has accessed the fuel pump by cutting it through the floor, and what the dimensions would be. Thanks.

 

Hi guys new here. I have to replace the fuel pump on my 02 envoy. Should I drill 4 holes in the floor around the fuel pump and then use an air chisel to cut it out? I will replace the cut out section with a larger piece of metal since no one would see it once the rug is back down. Thanks Bruce.
