Factory service manual showing a
pump made to be rebuilt.
First step was to buy a new Carter M4553 Fuel Pump, RockAuto
$22.79, plus $6.25 shipping (air filter was included in order so S&H may be
higher than normal.) These newer pumps are crimped together and are
non-rebuildable. This pump features a one year warranty.
The fuel pump mounts low on the
passenger side front of the engine. This is probably easier on a non-AC car.
While at this point the car has been in my care 11 years, the pump predates the
car going to the junkyard so it was on the order of 17+ years old.
Hoses get disconnected. Careful on
the one from the tank; since it is gravity fed you need a bolt to put in the
hose or a clamp to keep the gas from pouring.
Both hoses disconnected.
View from the bottom. The fuel
pump is held on by two bolts. Removing the motor mount to accessory bracket
bracket to the right gives you the room you need to change the pump.
This is how I got the the front
bolt. Back bolt came out from the bottom.
New versus old. When the old one,
right, was re-installed in 11 years ago I didn't know to grease it, so the wear
Here is how the old one is
suspect. If you look between the rocker arm and the body, it is really clean,
where the gas has solvent cleaned the oil off.
View of the rocker arm just as
clean where it shouldn't be.
The pump was leaking both
directions. While I had it on the floor this giant puddle of oil came out of two
vents holes which are past the oil seal.
See that gold ring in the oil pan?
That was sediment that drained out of the old pump.
I was impressed that the two bolts
still had a good coating of anti-sieze from 11 years ago.
Clean the old gasket off.
Another new vs. old. The outlet
fitting gets transferred to the new pump. I tried to use teflon tape on it but
adding it wouldn't allow the fitting to thread in, so I went without. No leaks
have been detected.
Pump gets coated for the gasket.
Gasket installed and sealant
I had wheel bearing on hand to
lube the rocker arm.
Dab will do.
Reconnected from the bottom side.
From the top.
Don't forget a new fuel filter.
This one is a Wix 33040 for A/C cars. It was $6.49 at O'Reilly Auto.
