SU FUEL PUMP RESTORATION

In the process of restoring a fuel pump, the following is accomplished.  The fuel pump 
is completely disassembled and inspected.  Any part that shows excessive wear or 
breakage is replaced.  The points are replaced with a magnetic reed switch and a magnet.  
The magnetic reed switch is a magnetically operated switch that is sealed and filled 
with an inert gas to prevent burning or dirt build up on the contacts.  The diaphragm 
is checked for any signs of leakage and stiffening - it is replaced if there is the 
slightest question of it's continued satisfactory operation.  The valve disks on the 
low and high pressure pumps used on the 'T' series MGs, MGAs and early MGBs are replaced 
if they are deeply grooved, otherwise they are lapped smooth and flat and polished.  
Likewise, the valve seats are polished.  Valves on the AUG 300 pumps that are used on 
the later MGBs are checked for proper sealing, and replaced if they are defective.  The 
coil is removed from the housing and the wiring checked and renewed if necessary.  The 
coil housing and pump body are cleaned, bead blasted and the coil housing is painted.  
The cap is cleaned and if necessary, buffed. All threaded screw holes are cleaned and 
a tap run through them to insure that the threads are sound.  Any threads that are 
damaged are heli-coiled to restore them.  Finally a serial number is stamped on the 
pump body for tracking purposes.

After cleaning and painting, the pump is reassembled, adjusted to factory specifications 
and converted to solid state.  During reassembly,  all new gaskets are used and all 
joints are sealed to insure they are air tight.  Once reassembled, the pump is tested 
for air leaks and then placed on a test stand and the current draw, fuel flow rate and 
pressure are measured and recorded.  Then, the pump is left to run continuously for a 
minimum of 8 hours to insure that it will continue to operate satisfactorily.  It is 
then emptied of the kerosene used on the test stand and the ports are plugged to preclude 
any foreign material getting inside during shipping.  The pump is shipped with a record 
of all parts used and the test results, along with any observations I may have made that 
I feel you should know (such as rust in the pump that would indicate that your fuel 
tank/lines should be cleaned).  I keep a copy of the data on your fuel pump on file for 
future reference. 

The charges for this service is $40.00 plus parts and shipping.  Depending on what parts 
are needed, the total price has been running $50.00 to $80.00.  After the pump has been 
dissembled and inspected, I send you an estimate of the cost and wait for your 
authorization before proceeding with the overhaul.

When restoring and converting the fuel pumps, I use magnetic reed switches and a magnet 
in all pumps.  I do this because, once converted to solid state, the current flow through 
the points is so low that it will not burn off any dirt or film that develops on the 
heavier original points. In addition, I place a label on the pump showing the ground 
polarity the pump must be used with.  If you are going to change the ground polarity of 
the car this pump is used on, the transistor in the pump must be changed and the diode 
reversed or the pump will not work and the transistor will be damaged.

There is a one year warranty on parts and a lifetime warranty on labor on all pumps that 
I restore.
