Carter Dual Action Fuel Pump Rebuild Part 6 - Assembly
Finished
December 4, 2010
The next part to install is the piston for the vacuum pump. If you have
not already done so, install a new o-ring on the piston. Lightly lube the
o-ring, shaft, and piston bore with engine oil and place the piston into the
bore. Use a thin feeler gauge to work the lower edge of the o-ring into the
bore. Once it is started, a few light whacks with a hammer will push the
piston down. Once that is done, set the new gasket into place.
Set the large spring on top of the piston and line up the cover. There is
a vacuum passage next to one of the screw holes so it only goes on one way.
Push down on the cover and install the screws being very careful not to
cross thread them. Make sure that you keep tension on the cover until all of
the screws are started. Doing this will keep the cover from warping. Once
the cover is in place, install the fitting for the vacuum line.
The last thing to assemble on 1968 and older pumps is the fuel filter.
The picture below shows the parts that make up the filter assembly. You can
obviously do this in the car but it is far easier to put the pump upside in
the vice and do it before you install the pump. The order is: gasket,
filter, spring, fuel bowl, and retainer. Once it is installed,
gently tighten the screw in the retainer. One turn past finger
tight worked for me. If you tighten it too much, you'll ruin the fuel bowl.
The filter I used is Wix #33038. This was readily available at a local parts
store.
The only thing left to do is install the pump on the car and change the
oil. It would be a good idea to put a little assembly lube on the pump arm
before you install it. The only trick to remember is if the pump doesn't
want to go in easily, turn the engine a little bit to take the tension off
of the pump arm.
