Burb Gas Tank for EFI Conversion? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**RoyL** · 01-05-2022, 10:11 PM

Have seen several threads on the 63-66 pickups and underbelly tanks, but not many focused on the Suburbans... Looking to do a "LS" swap (5.3L from 3rd Gen GM truck) on my 1965 Suburban and have been looking for a replacement tank with in-tank pump. It looks like there are a few options I've seen, but not all are setup for the in-tank pump.

Rick's Tanks - GM TRUCK 1963-66 - Part #135001 Side Fill, 135002 Cap Fill, 135003 Bed Fill. Does not list Suburban but says it's side fill. Does it work with the Suburban?

Boyd's welding - Does not list Suburban but says it's side fill.

No Limit - 19 Gallon. Not Suburban specific but has side fill option... We can outfit our tanks with a side fill port for those who want a clean bed floor. Typically a custom door is then installed into the bedside or fender. A small "c" notch (included) may be required for frame clearance.

1991 Suburban tank - I believe it's an EFI tank but for TBI, pushing <20 psi? Is it easily converted to a higher flow pump?
I haven't seen any specifics where someone with a 63-66 Burb have installed one of these. I read thru all the more recent Suburban build threads in this forum so I can't say I've read them all... Wondering about what fitment issues are there with the side fill location of the 1991 tank? How does it line up with the existing fuel door on the 63-66 Burb?

Other ideas I ran across but would require running an external pump:

Brothers Trucks - 1963-1972 Blazer/Suburban Gas Tank Installation, using a poly tank. https://blog.brotherstrucks.com/1963...-installation/

'70-72 Blazer tank - What other years? Have read that the Blazer/Suburban tanks hang too low for some folks liking. http://67-72chevytrucks.com/vboard/s...d.php?t=621177

Anybody converted their original tank for an internal pump? to keep the spare under the truck?
