I have a old Harwood fuel cell in my Camaro, I purchased new back in 1992, lol. Looking for a upgrade. The Harwood is a 15 gallon with sending unit, it has only one outlet and no rear sump, bottom is flat. The outlet goes thru a hole in the trunk where the old filler tube used to go thru, I am looking for at least a 12 gallon with sending unit, rear sump is ok, I can raise the cell up, don't want anymore holes. What is everybody using?
