does anyone sell a factory style fuel tank with a sump built in already? I cant seem to find anything for my duster Probably not I had a local custom car builder shop build and install one in a new Spectre brand tank for my 1971 pump gas street Duster. Look around to find a add on sump you like and see if a local shop will install it for you on your existing tank or if they want you to buy a new gas tank first for their own safety The shop that did mine used a round top off of a small (5 to 6 inch diameter)automotive air conditioner reservoir I think, they welded in a 1/2 NPT bung and I ended up using a 1/2 NPT to #10 AN steel nipple in the bung to feed my fuel pump mounted behind the sump. The sump stuck up into the tank around 4 or 5 inches and had a number of 1/2 inch holes drilled in it to allow fuel to get into the bottom of the sump, it work very well

what should be done to an old tank to weld a sump in? just clean it out with some degreaser or something? maybe fill it with co2 and seal it up before welding?? I believe they fill it with water.

Why the sump? That's ok for a dedicated drag car if the sump is properly placed and plumbed correctly, but for spirited street or road course driving; it's less than ideal.
If you are trying to keep cost down, add a return line to your sending unit, plumb a small lift/pusher pump just outside the tank to a small surge tank, and plumb it on up to your motor.
A simple surge tank system will deliver air free fuel down to the last gallon and out perform a sump set-up every time, especially if you run a Holly Hydra Mat in the tank.

I have been running that Summit sump on a factory tank for several years & it works great. The only complaint is very limited ground clearance if you have to put the car on a flatbed truck, facing either direction.
I used a hardware store hole saw to cut holes into the bottom of the tank and a local radiator repair shop welded the sump on.
