Why bother! The mechanical pump you currently have has worked well on a multitude of Jeeps and AMC and Mopar vehicles. The reason the manufacturer went to an electric pump was because of fuel injection. The mechanical pump is easy to change if it fails, which it seldom does.I took the old metal tank out of my 89 and used a 20 gallon tank for a 94 or 95 YJ with the in tank pump. It needed a supply and return line so I used a corvette regulator mounted to the frame back by the tank therefore only running one line forward to the fuel rail. The only thing different was I was feeding a V8.YJ Fuel Line - Rubber hose section. 89 YJ 4.2L. Leaking fuel line and not sure what size or how to get the clamps off to replace the line. There are 2 short hoses that are on the driver side engine, one goes from the metal fuel line to the filter and the other line goes to the mech fuel pump on the passenger side.dodger889. 4184 posts · Joined 2009. #2 · Nov 30, 2010.
