MG MGB Technical - Fuel Pump: Leave well alone, restore or replace??

Recent troubles with my car i think have highlighted that my fuel supply system could probably do with a bit of an overhaul.

I need to sort out the earth to the fuel pump and i have a leak from some of the metal fuel lines where the clip has worn away/corroded?? the pipe, this appears to be making the pump rather noisy.

I was wondering whilst at the same time, whether to take the fuel pump out to give it a bit of an overhaul?? If i did, how easy is it to overhaul - is it worth the hassle, or shall either exhange for a new one/recon unit (saving me some bother) or just leave well alone? It only appears noisy due to slight air leak and was previously running fine - shall i leave it??

I bought a brand-new SU pump, points style for
about $90 US and am quite happy with it. Note
that there are inferior plastic-bodied pumps out
there. The genuine ones made by Burlen are metal.

If the pump is original, it's probably worth replacing.

If the pump is working without needing to be beaten with a screw driver ever now and again then I wouldn't do anything to it. If you do have to convince (beat) the pump to work sometimes then you may want to try replace the points ($8.25 from Moss). If its anything like a MGA pump then it is very easy. In the long run if the pump has problems then you are probably better off getting a new pump.

My dad's MGA had a pump that needed convincing ever now and again. The problem returned in a month or two even with new points. We ended up getting a new pump and its been working great for the past 4 years. I took the old pump apart so many times that I can now take it out of the car, take it completely apart, put it back together, and put it in the car in only a few minutes.

Phil - Go to the following web site for some insight into the SU fuel pumps: http://www.custompistols.com/cars/articles/dd_su_fuel_pumps_101.htm
The ground for the fuel pump is under one of the nuts of the mounting stud for the rear license plate bracket. This is a place that corrosion tends to form, so I would suggest undoing it and cleaning the surface very well and even coating it liberally with a good dielectric grease. Steven is correct when he says that if you don't have to beat the pump with a screwdriver handle to make it work, then it is best left alone. Good luck - Dave
