Fuel Tank Mods

Has anyone successfully added a "bowl" into the bottom of a steel tank to get away from needing a swirl pot when going to injection? Seems a better way to do it and will be running a return-less fuel system anyway. Its a Midget tank i have installed

I've got a mini van tank, with a mondeo pump and bracket installed through the top. The mondeo swirl pot was too large to put into the mini tank, initially i used it as was, but there was fuel cut below 1/2 tank, as the internal baffles were not sufficient.
To rectify, i made a smaller swirl pot out of thin steel tube with an elbow for the pickup filter at the bottom, and some fuel resistant rubber discs in cutouts to allow fuel in at the base, but not back out.
Just jiggling this about in fuel would fill the pot, and the return is also into the pot, i've not had any issues with fuel cut since.

Iíve welded a steel fitting to a steel tank. I canít say it was the best decision Iíve ever made but I did it anyway. The issue is can you be sure Itís clean enough. The consequences are high if itís not.

I would also want to Tig it. Getting away with it once is one thing. Having to try again due to pin hole is another.

Iíve just replaced my fuel tank with a midget tank and now am suffering fuel starvation after left hand corners. I guess the tank is just so shallow it doesnít take much to expose the outlet. Iíve been spending more money than Iíd like on it recently so hoped I could avoid additional work of a swirl pot. I was wondering about the effectiveness of the foam cubes you can use in the fuel tank.
