MG MGA - Billet fuel pumps.
|After the second failure of my SU fuel pump in two months due to point pitting I am looking to replace it with a Billet type electronic one. Can I buy a positive earth Billet pump? Is it possible to buy adapters to screw into the Billet pump and still retain the brass hose connectors? |
I wish to retain the positive earth system as I run a positive earth Pertronic distributor. (I intend to rebuild the old pump to use as a back up) Does anyone know what the value of the capacitor in the SU pump should be?
|Dave - I would discourage the use of a points style SU pump as a backup pump. The problem you will find is that after it has been dormant for a long period of time, the points will have filmed over and the pump won't work when you need it. I am not familiar with the Billet pump, but if it is an electronic pump, it would be a better backup pump as there is no points in it, so it can sit for many years and still know that it will work when it is needed.|
As for the capacitor used in the SU fuel pumps, I believe that it is a 0.35 microfarad, but a better component for arc suppression is a TVS diode (also called a Transil diode), P/N P6KE27CA. This particular transil is dual polarity, so there is no worry about which way it is installed. Cheers - Dave
|Sorry Dave I should have said Facet not Billet. Note what you say about SU pumps as backups. Wouldn't a smear of dielectric grease on the contacts before storage prevent a build up of film?|
