I have 1967 Pontiac GTO that I am considering adding throttlebody EFI to help with starting and fuel odor in garage issues. It seems like the best way to deliver fuel is with a intank fuel pump style reservoir. All of the tanks I have seen so far say 1” deeper than stock, even the brand that advertises theirs as stealth. I assume the intank pump requires the space for this the modification. If someone has tried this installation on your GTO or Lamnas can you please tell me if the 1” added depth is very noticeable on the car? I would prefer if my car doesn’t look like I am attempting a Cannonball run.

The aftermarket EFI tanks may be slightly deeper than factory in some cases, but it would take a really trained eye to notice that it's not a factory tank. If you're worried about concourse judging with something like that, the simple addition of the efi throttle body itself is going to knock you as well, so there's no real reason not to go with the efi ready aftermarket tank.

I've had two tanks inc tanks myself. The one in my firebird is 10 years old and is still in outstanding condition. I also had a tanks inc tank for my wife's 70 Chevelle. Although we no longer own that car, it also held up really well. In the case of both tanks they were both very close in size, shape and design to the original tanks they replaced. I can't comment on if that's the case with their offering for a 67 A-body.

HAHAHA...funny you mentioned "Lamnas", cuz that's me....!!

I have a '65 that I'm putting in a tank from Rick's. Probably going to do it this week, so it's not in yet and I can't comment directly. The tank is close in appearance to an original (at a glance), but there are a few dimensional differences. Maybe I can get a side-by-side pic when the original is out.
Mine is a "Restomod" tank and has a bit larger capacity vs an original 21.5 vs. 22 or 24...can't recall exactly....therefore the straps are similar but different to accommodate the slightly larger size. It's not the correct galvanized finish, but actually looks to be a silver powdercoat...and then of course there's the recessed area at the front on top for the pump hat and sender. A couple of vents, too.

I will add this: I did a retro mod kit to drop in an efi pump into a stock tank. It works, but probably not worth the trouble to cut the hole, etc.

Looking back, I would consider doing either the well engineered EFI ready tank, or run an external pump back at the tank, and feed my return style regulator.

The reason for the external pump lament is the PITA to change out a fuel pump, and the noise during priming. I'd rather have the external with 6AN fittings on everything. Gonna guess pump cooling is better in the tank, so who knows.

I put the Holley muscle car fuel module in my 66 tank. It's basically a TI 250lph pump with a holley hydramat and stock style float level. It also has a 60psi regulator on the end of the pump so it returns straight ontop of the pump and you just use the factory 3/8" line to the front. It's a very clever and clean design and it works very well too. Would I use it in a racing application? No. The stock tank is just a big flat wide chamber without any baffling, but on a street only deal i've had zero issues. The hydramat just works.

Rick’s stopped making the Restomod tank. Too bad it was the best system out there for EFI conversions. He used a GM Camaro fuel pump that has an internal regulator and no return is needed. I had so many issues using pumps that Holley or tanks supplied

I use tanks inc. Have them in 5 of our cars. Nice baffled tank.

Far as I've seen the f body tanks come both standard and oversized. I always go for the oversized if offered. I like the extra 3-4 gallon capacity. And on the fbodies I've done it's not really noticable. The sump is more towards the front of the car. Not seen very well from the rear as the tank slants. In fact I did an oversized 21 gallon f- body tank in our 73 Vega and even in that little car you don't notice it

To add, I haven't found the extra capacity tanks available for a- bodies from tanks inc. just the standard 20 gallon deal. Both of our a-bodies have the standard EFI tanks because that's all the they made at the time.

Unless they have a new offering that was recently added for extra capacity a body tanks. In Which case I'll be switching mine.

The pumps work in either standard depth or extra capacity

Yes this set up was the best. You can find some scratch and dent ones still on ebay. Those pump on a stick set ups burn up. The large AC Delco pump is ideal by far.

Rick's site still showing some though:

Thank you for the replies. I think the Tanks Inc based on baffling. Aeromotive has a stock size tank, but it looks like they use a foam baffle. Really appreciate everyone’s input.

Sorry, I meant to post thanks for the replies.
