i put a new OEM pump on this truck last year.I have replaced all of the filters. i guess my next move would be to replace the rubber fuel lines.i replaced the ones under the hood,but not coming from the tank in about 15 years since i last had the bed off for a paint job. will i have to remove the bed to replace the rubber lines coming from the tank. nd i will drain that tank .thats a good idea. i have not done that since i have had the truck.
