Installing a 1991 Blazer gas tank, body lift?

Hey guys,

I am putting a 1990 Corvette TPI engine in my 1972 Blazer (4x4) and I have purchased a 1991 Blazer gas tank to put in too. I know I cannot use the stock electric fuel pump from the Blazer because TBI has a much lower fuel pressure than a TPI.

I remember a few guys had done this gas tank swap but as I recall I am going to have to move my rear most cross member back and I thought a 1.5 inch body lift was also recommended. Has anyone done this swap? Any info, or any thoughts are appreciated.

Thanks,

Rod

I started trying to use the same tank you've got when I swapped over to injection myself but ended up going fuel cell, turned out much better IMO.

More money up front going fuel cell but you get a better fit without the headaches and at the same time, the right pump for your TPI too.

A board member by the name of 'Fuel Cell Guy' makes em for our year blazers.

Great guy, he'll even custom build one to your specs.
