Burb Gas Tank for EFI Conversion?

[RoyL]

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.
https://fueltankparts.com/collection...ealth-340-pump

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:

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

I have not seen anyone reproducing a 63-66 burb tank with the proper spare tire cutout. The usual aftermarket tanks do fit in the stock, burb location, so that's probably why all the vendors say it is for the burb

Here is info on one from Holley you might find helpful:

Thanks! This one and the Tanks one look similar, would like to find someone who has installed one of these side fill tanks on a 63-66 Suburban, to see how the side fill lines up to the stock Burb fuel fill port.

I'm fairly certain you will have to do a little custom fab work to mate back up with the original filler regardless of which tank you go with. The positive is that you will have a brand new tank with modern internals (and potentially a brand new filler tube to the side fuel door), well worth it imhp. Keep us posted on your progress and good luck!

Roger that, appreciate the feedback! Given long shipment times for parts these days, I want to try to make sure I get it 'right' the 1st time. For example, $584 for a Tanks one with pump and sending unit vs a Boyd's tank with all that installed for ~$250 more? Which one requires less fitment issues to deal with, requiring fab work and/or additional parts. I know this is all part of the hot-rodding experience, solving these issues, but don't need too much of that... lol

For example, Tanks has a bunch of filler hoses of various shapes, https://www.tanksinc.com/index.cfm/p...rod/prd104.htm
Maybe I'll be the first to do this and get to report back here.

Thx, are the pick-up and Burb frame the same where the stock Burb tanks fits?Would be nice if these aftermarket ones used the same one-strap design as the Burb. Lots more Pickups than Burbs I reckon.

Yes, the frame is the same where the gas tank mounts. I believe the aftermarket ones use the two strap design similar to the 67-72 Burb.
There are lots more pickups than burbs, and since the frames are the same width as the 67-72 burbs, the aftermarket companies don't spend the money to make a tank with the spare cutout

CPP makes one with intank pump for EFi, no cut out tho.

Which one? This one @$1,162? SS but does not include the EFI pump or sending unit...

There's one that's intriguing, says for Suburban, 26 gallon, but not EFI.

Clyde,

Nice truck! Do you have another photo of your truck from behind? http://67-72chevytrucks.com/vboard/s...2&postcount=75
I see you have a Boyd's tank, wanted to see if it's visible hanging down?
Thx!

Hey Roy,
I am also looking for the best fitting tank for a 66 GMC suburban (carryall).
What I notice on all the side mount aftermarket tanks is the side fill comes from the top and not really the side like the originals. I think there might be a contact problem with bed boards plus a slower drop to the tank when filling because of the angle to the filler door. And nobody wants one that hangs below the bumper. Mine has a 1995 TBI engine so I also would want an in-tank pump.

Perhaps there would be enough interest in these that some company might custom make one that addresses all the issues and would work for all the suburban/carryall owners.

Please keep us posted on your experience and I will search also for custom fab...

I installed a boyd efi tank on my 63 suburban for my ls1. I had them change the fill location and the size of the fill pipe on the tank so it matched right up to the original fill pipe. the tank works good for my application. My suburban is lowered in the rear 5ish inches and you cant see it that much from the back. i can take pics if you would like for reference.

[Clyde65]

RoyL,

Thank You!

Here is a rear view of my truck.

RoyL, here is the tank I got.

Yes, photos are always much appreciated! I know it's close quarters under there, I could not get great clear pics of the stock filler plumbing...

Clyde,

Thx, can't see the tank hanging below your bumper... that's good to see. Looking at the link, it's a Suburban 26 gallon tank, there's a sketch with dimensions, 13.3" tall and 21.3" long. Is this the one you have?

The C10 tank is 20 gallon, 11.4" tall and 19" long.

clem,
Thanks for joining in on the discussion, will also share whatever I find and end up doing. You said you have a TBI, so you may have option of a Suburban tank from the 90's, I can't find the link where someone said what year(s), but they would already be set-up for the TBI pump in the tank?

Here are the pics on my burb...Boyd tank with altered fill to match up to stock fill location.

thanks for the pics! Looks like the filler and vent are a straight shot to the new tank, no turns? Do you have the dimensions of off-set from the boyd's "stock" side fill tank?

What capacity is your tank?
Thx!

Looks like the filler tube is about 10" from the rear brace

[lownslw64]

The boyd tank is 19 gallons, My fill is 10.75 to center of pipe from front of tank and I left how it was placed from side to side in their standard location. It would be to your benefit to move that in a inch or two so when you install you can put it straight up and not have to angle into position. The pipe size is 1.5" also. The only issue i had with this setup is i also bought the rollover vent i think it's called but due to the location of the fill it would keep it closed when filling and not allow the tank to breathe causing it to always shut off. i ended up taking it out.

All us 60-66 Burb owners sure appreciate the info, feedback and pics you have shared to date. I am curious about the roll-over vent you removed.
-How is your tank vented now?
-Are you using a vented gas cap? if so which one and do you get any gas seepage/spill on spirited turns?
Thanks!

Thx for the info! Can you please clarify what you mean by the above in blue?
Confused as to where the "standard location" is?
