Gas tank help

Heres the deal, my 85 GSL (daily driver) has a pretty good size gas leak. I have a gas tank from an 82 that is in much better shape but it is dirty inside. I plan on taking it to a radiator shop and having them clean and recoat the whole thing. I got quoted $85 for it. The catch is that I am going to go EFI (Megasquirt and DCOE style throttle body) and I'm wondering if I would be better off trying to get an FC tank with internal fuel pump which I probably wouldn't be able to have cleaned and coated by a shop because of the baffles (I think they are plastic) or whether I should have the 82 tank cleaned and coated and use an external pump like the GSL-SE. I'm a little concerned about going around left-hand turns with that tank with EFI.

Any suggestions? I'd like to make my decision by tomorrow morning.

Gas tank

Use the 82 tank. If your worried about fuel delivery, don't. The se pump will not have any problem keeping you properly supplied.

I think he's worried about slosh.

I run a regular tank with an FI motor. Slosh is not that big of an issue. It happens, but not enough to make me run out and change the tank, and I even have an -se tank laying around!

Slosh definitely was a problem for me. If the tank dropped to about 1/4 or less, the engine would studder going around corners. Switching to an SE tank fixed it.

$85 to seal the tank is a great deal, by the way.

Some put a solvent in the tank with a large chain and have a friend help "mix it up" getting all of the loose crap knocked into the solvent. The dump the solvent rinse: let dry: and put "gas tank sealer" in and slosh it around coating the whole tank and voala.

thanks,
So that's what you guys use for outhouses in Bc.
Sorry , had to jump on that one.
Take to radiator shop and have it boiled out, then pour in sealant called por12 then you are done. And that's no crap
