Installing a 1991 Blazer gas tank, body lift? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

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
