MG MGB Technical - 77 MGB Fuel Pump Noise
|Bought the car two weeks ago. Been re-doing some bits, etc. Re-built the brake master cylinder and was able to get the machine out on the road for a test run. |
The fuel pump gives off a continuous clicking sound. Plainly audible when cruising. Annoying. I havnt looked at it yet. I am wondering if it is mounted wrong e.g. should have rubber isolators, or is this normal noise? Maybe its getting ready to go?
Any thoughts would be helpful. Thanks in advance.
|you may well have an aftermarket electronic fuel pump --they will click continuously. The SU usually only click audibley when ignition is first turned on.|
The only way to be sure is to locate your fuel pump and see what you have.
|Thanks Gil. I will check it out this weekend and report back.|
|rj - Your car most likely has one of the little, square, run all the time, make a lot of noise Facet pumps rather than the original SU fuel pump. You are faced with a couple of alternatives if you don't want to put up with the constant noise. You can purchase and install a proper SU fuel pump or you can get some sound mounts for the Facet pump from Pegasus Racing at: http://www.pegasusautoracing.com/advcat.asp?CategoryID=AIRFUEL|
Click on Fuel pump accessories and scrol down to mounting kit. If you want to replace the pump with a proper SU fuel pump, I have several that have been restored and converted to solid state that I can sell below the price for a new pump.
A final alternative is to keep the Facet pump, sound mounte it and route the fuel lines from it to a proper SU fuel pump, then on to the carburetors. Install a switch for switching power from one pump to the other and you will have a back up pump that you don't even need to pull off the road to get you home in case of failure of the primary pump. Good luck - Dave
