Vacuum Fuel Pump - Cont.

The incredibly warm weather this December made it possible to attend to some project clean up.  To complete the fuel system I needed to drop my fuel tank and repair my gas gauge.  I also removed the wood floor to get to the fuel line and mate it with my new vacuum fuel pump as well as install the remaining mechanical task, the drive shaft.  After all this is done everything else is esthetics.

The Fuel gauge was a little bit of a struggle.  I had the remains of an original gauge which I repaired by soldering the standoffs to keep the mechanism from jamming.   After much consideration I decided not to use the original gauge because my remaining original components were too deteriorated to seal properly so I decided to use the ford reproduction which works OK with modification.  Since the float was stuck I needed to tweak the position 180 degrees.

Here is a link to a 2008 repair report that shows how I incorporated this gauge.

Gas Gauge Repair 2008

This gas gauge may not be original but will definitely not leak gas while on the road.

It's really nice to be able to remove the flooring to work on the bottom side of the car.  Since the weather was accommodating I was able to paint the underside of the floor with a good exterior black paint.

You have to love a 57 degree day in late in December.   There are 3 floor sections the picture shows only two.

With the gas tank back in the car I finished the gas line to the Vacuum Fuel pump.   I decided to mate the original 1/4" copper to a run of the new style copper/nickel tubing to finish the run to the pump.  I did this because the line had no leaks and used an old style compression fitting to mate with the fuel tank.  Since it wasn't broke I didn't fix it.  A code I live by.  I also ran a 3/16 copper/nickel vacuum line back under the dash to supply a vacuum wiper motor for the windshield.  This is an important item in order to get my car approved for driving on state roads.

All this copper tubing looks great.  I will find out how well it all works later next month when I hopefully drive this car out of the garage for the first time in a little over three years.
