So many choices. What have you done for a bolt in tank with fuel pump for an LS turbo run by Holley Terminator X Max.

If you have a GN you don't need a new tank. Throw a new pump on the sending unit and give'r
I do not have the original tank anymore. It is an 87 GN.
How about a replacement tank from Tanks Inc or Holley. Then what are my pump options?

Walbro 450 or 525 for an NA car. Holley has pumps as well, but the reviews are not super.
Spectra GM307C is the replacement tank for the factory 84-87 Turbo Buick baffled tank. The best intank pumps I have found have been the ones from Racetronix as sold through Full Throttle Speed.
Tanks Inc, Spectra, holley all have repop 'baffled' GN EFI tanks. I have seen photos that show a OEM GM tank has better baffling than a spectra tank but I've never had an issue with my spectra. As long as you aren't dumb and don't autocross at 1/8 tank you are fine with the spectra.
I have no way to validate this but I ASSUME all the tanks are stamped in the same place. Holley/Tanks Inc likely would not have spent the tooling to make an entirely new tank. The tanks inc one has a separate insert in the stamping tooling to use aftermarket senders/level sensors but from everything that I can tell it's the same thing.
I know 100% the spectra tanks have issues with air discharge during fillup. Not sure about the holley tanks but it's probably all the same manufacturer of the stampings and it just gets relabeled.
If you have access to an OEM GM tank it's often better to keep the old filler neck and solder it to the new tank. I've done it with both my EFI swaps and had no issues with alignment or burping fuel on fillup.

I don't think it's the filler neck, I think is the roll over valve in the sending unit. I just drilled mine out and it made a huge difference.

The dual 450 can support a lot of power, that's what I have, albeit home made
But I don't understand
a) how do you get 2 pumps through the tank hole at the same time when 1 barely fits
b) there's no way that fits under the stock trunk without cutting the floor, I had to dent one of the reinforcement ribs in the trunk floor to fit 2 -6 feed lines coming out of the tank. I fail to see how a -10 fits
