Fuel tank from later model 'Burb??

[-Greg72]

My searches here have revealed a number of sources for aftermarket tanks (the ECE Stainless 27 Gallon one is beautiful)... and I've seen a few other options in the 20 - 24 gallon range.

My '72 has it's original "factory option" 50+/- gallon fuel tank. It's a monster and hangs lower than I'd like...and there is no provisions for a return-based EFI setup (obviously). The ECE tank is a great looking choice, but with a thirsty 496BBC going into this build, 27 gallons really isn't going to give me much range....at least not the 300-350 miles that I think would be reasonable.

I've seen some late model Suburban tanks that are already set up for EFI with the necessary fuel returns, and IIRC at least one of them comes in around a 40 gallon size.

My question is if anyone here has ever tried to install a late-model GM fuel tank in one of these older Burbs....or is it just a total fitment nightmare??
