Making that fuel pump last

In my line of work, I have replaced countless in tank fuel pumps. In tank fuel pumps are submerged in fuel in order to help them run cooler. I see many people out there (especially with today's gas prices) who run their vehicles on the empty side of the tank. Empty tank=hot pump. It's just as easy to keep the top half filled as the bottom half. Keeping adequate gas in the tank in conjunction with a regular filter change will insure your pump will last it's longest.

GOOD POST!!


its the fuel sloshing around in the tank that cools the pump, and it takes a minimum of a 1/4 tank to keep it adequately cool for max life. adding a bit of marvel mystery oil to the fuel, with its solvents and lubricants (about a pint per tank) helps keep the pump and injectors running smoothly with less crud and better lubracation

IF YOUR LOOKING TO JUST REPLACE A DEFECTIVE PUMP ILL OUTLINE THE BASIC STEPS

its not necessary to drain the tank but its a good idea to do so,
step one have the parts on hand PLUS 3 ft of 3/8" fuel line and 1 ft of 5/16" fuel line , I know, you may not need the fuel line but in many cases its faster and easier to remove the old line and replace with new ones
hose clamps, youll want several 1/2" size for the lines

(optional but a GREAT IDEA)

ok, step one,
make darn sure the keys are out of the car and the battery is disconnected for extra safety

step two, open the fuel fill door center rear deck where you normally fill the car and remove the gas cap

step three
remove the four very small torx screws in the corners and lift off the door assembly

step four
theres a rubber bib fuel spill tray)(around the fill spout, remove the gas cap and work the bib fuel spill tray ) (out , and disconnect the water drain line and label it with masking tape/pen

step five
label the three lines with masking tape/pen (upper line/lower line /left side line)
remove each at the central point in the opening, then disconnect the electrical connector on the lower edge of the opening

step six
remove the 8 10mm bolts and look carefully at where the components go, after they are removed the pump lifts up and out, the pump normally comes with instructions also, but its fairly simple, the pump, lines and fuel level sensor lifts out as a sub assembly, look thru the link below for pictures and more info
