Re: Will 1987-1991 blazer fuel tank work?
Does anybody have the part number of the sending unit? I plan on putting one of these in a Suburban that I am doing a LS swap on. I would guess that the sending unit is the standard 0-90ohm?

Re: Will 1987-1991 blazer fuel tank work?
how can one find out which sending unit you need ? I know there is 2 inch difference from 25 to 31 gallon tank, do you measure from the pan or from bottom of the inside

Re: Will 1987-1991 blazer fuel tank work?
Bringing this back up for information on the connections to the in tank pump. I don't want to run AN fittings. Looking for either a barbed fitting for EFI rubber hose or possible the newer style nylon fuel line.

I installed this tank in my 72 with AN Fittings. I bought the sending unit from rock auto. They had sending units that used barbed fittings as well.

Re: Will 1987-1991 blazer fuel tank work?
For anyone else looking into this the 92-96 31 gallon tank appears to be identical except the filler neck is on the opposite side but doesn't have the 90 bend on it.

Re: Will 1987-1991 blazer fuel tank work?
It's likely the ohm on the sender. Here's some good reading.

Filler neck hole is on the correct side for the first gen k5. I need a tank in mine and would like to go ahead and get a bigger one that would work for a further LS swap but could also work for now with my stock 72 motor and fuel pump. Anyone know if I can buy the stock 96 fuel pump/sending unit then pull the fuel pump out and replace it with a piece of fuel line. Rely on the 72 fuel pump then, to suck from the new tank just like it does with the older set up. That way I could go back to the in the tank pump when I do a LS swap later?

Re: Will 1987-1991 blazer fuel tank work?
Not sure, the plan would be to have a filler neck welded on to fit the first gen if needed if the stock tahoe one wouldn’t work. Maybe pull a filler tube from one from a junkyard to save some $. I’ll buy a new tank though

Re: Will 1987-1991 blazer fuel tank work?
After doing some measuring the 92-96 tank won’t fit. It’s too wide to fit between the frame rails. I measure the width between mine at 27 1/4”, the stock tank and the 87-91 tanks are a little wider than this but only with the flanges. Guess it’s back to the 87-91 for me and having the filler next swapped to the other side on the tank or turning it around.

Re: Will 1987-1991 blazer fuel tank work?
1 3/4" looks to me. You measure the diameter below the ridge though, least I do with a caliper
