| 摘要： | If you do see dirt, rust, or other contamination in a fuel tank when you're ready to replace a fuel pump, drain and remove the fuel tank to perform a complete cleaning of the tank. If you can't figure out how to get paid for all that work, or the fuel pump R&R can be done w/o pulling the tank, at least use a fuel tank cleaning wand that has scrubbing pads with magnets to pick up any ferrous debris from the bottom of the tank. In either case, always do as deep of a fuel pump autopsy as (time and warranty return part rules allow) to try to determine what killed the pump. The last thing you want to do is continue throwing parts at the vehicle/be in denial about the number one enemy of fuel systems - contamination! Until street sweepers make a comeback and customers agree to only drive on paved roads, environmental (dirt) fuel system contamination will be the natural enemy to fuel pumps and evap systems. Cleaning fuel tanks (when applicable) will definitely help. A new (serviceable) aftermarket evap filter solution would be another idea. Until that comes along, we'll need to continue with the "dirty job" of dealing with fuel system contamination! |
