question about installing sumps
 

Since I'm having trouble removing my pickup/sending unit, I'm considering going with a sumped tank.
How do you clean the tank out good enough to convince the welding shop that it's ok to weld?
If I took it to a radiator shop, would they be able to clean it well enough to weld?

Rinse it out well with water, then take it to a welding shop. Any good welding shop will know enough to drop some dry ice into the tank while welding. The dry ice displaces all the oxygen so there's no combustible atmosphere. Only cost me $45 to have my sump welded in, including the cost of the dry ice. Also, don't let anyone talk you in to brazing it on....braze just won't hold well enough.

Jeff is right on this one! I looked into it myself, turns out my tank was shot. So I just got a new one for the $150 cdn it costed and had a friend of mine TIG weld it on. Not too hard of a job really. Haven't had any trouble with it, and that's two years now.
