i know how to do the one on the tank itself...what im stumped on is the nipples that go to the block. Since both of them are bead rolled. where/how can I get those fitting to accept -an fittings? are there special plugs out there the same size as the plugs where I can put -an fittings

 

Measure the diameter of the nipples (should be 1/2"). The take a tube cutter and cut the flare off of it. The you can get the fittings from Earls that have the tube to AN pieces. Essentially it is a crush washer that forms around that tube once you tighten it.

Similar to this right here. They do make a 1/2" one, I have a couple at home.

I cut the rolled part off the block fittings and welded on steel -8 male fittings. same with the catch can, but aluminum.

 

What he said^^^^ great idea. Or a -10 hose fits nice use a hose clamp to secure it.

 

thanks for the help guys
