I made a boo boo and ordered a spectra gm37efi fuel tank for my 72 Elco 5.3 swap. Well, I found out today that tank only fits 64-67. Luckily I am able to return it to rockauto for store credit because I've had it over 30 days. The major difference from a 72 tank is the filler neck location being too far forward on the spectra tank so it's definitely a no go. My question is, are there aby compatible OEM tank and pump options? For example, an 87 elco 4.3 tank with an f-body pump module? Tanks inc. Would be nice but I would like to use the rockauto store credit and unfortunately they don't carry the tanks inc.

 

Holley makes a drop-in module that fits a stock tank, returnless, as the regulator is on the module. Go to the Holley site under the fuel system section.
