I found an article by him about putting a Chevy fuel pump into a CJ 2o gal tank. It looked like the part was the stock pump that came with the Chevy Vortec engine, Maybe if you search for info on his engine Swap you can find out what year/model Chevy it came out of. Is that what you want to know? <img src="/forums/images/graemlins/confused.gif" alt="" />
