Do you have to take off the gas tank to change the fuel pump and filter on a 1999 chrysler lhs?
Yes. The fuel tank would need to be removed to access the pump and filter.
The fuel filter is under the alternator, you also have one in the carburetor. I got more fuel hose and moved the fuel filter to the fender with zip ties to anything there this way it takes 5 minutes to change the filter instead of 2 hours. also I only change the carburetor filter once every other year, or 4 (plastic) fuel filter changes.
