John McCormack Posted August 14, 2019 Report Share Posted August 14, 2019 The fuel pump is leaking oil from the pivot shaft. I would much prefer to fix it than put on an after market one. Any ideas welcome. Quote Link to post Share on other sites
RogerH Posted August 14, 2019 Report Share Posted August 14, 2019 Hi John, there should be a gasket between block and pump and I'm sure (but not positive) that it should have a slit in it for the arm to stick through. This should limit the amount of oil in that area. Also what is your crank case pressure like - it could be on the high side. Roger Quote Link to post Share on other sites
Ian Vincent Posted August 14, 2019 Report Share Posted August 14, 2019 If I recall, there is a small seal that prevents that happening. Rgds Ian Quote Link to post Share on other sites
stuart Posted August 14, 2019 Report Share Posted August 14, 2019 There is a small seal in the very base of the pump where the shaft from the diaphragm goes down through. Unfortunately its not available in the current kits though I think TRF in the US may have had it re-manufactured. Stuart. Quote Link to post Share on other sites
Ian Vincent Posted August 14, 2019 Report Share Posted August 14, 2019 I bought my pump reconditioning kit from an Australian supplier specifically because it included the seal. Rgds Ian Quote Link to post Share on other sites
Z320 Posted August 14, 2019 Report Share Posted August 14, 2019 (edited) Hi, you are asking for the shaft the rocker arm runs on? I put my pump out, cleaned it, glue one side of the shaft with 2K glue, next day the other side. This is sealed since I did that 4 or 5 years ago.

The kit sans seal from other suppliers is a bit over $10. Tom Quote Link to post Share on other sites
Hamish Posted August 14, 2019 Report Share Posted August 14, 2019 John just popped into the garage I hope these pics help. There is the usual card type gasket but also a vinyl type that is as Roger suggests a lot more of a slit but also a separate hole at the bottom of the slit. The size of a paper hole punch that just corresponds to a groove in the bottom of the pump to block aperture. I think it’s there to allow oil to drain back into the engine. The pump leaver will need some lubrication but with the “slit gasket” it’s not over the top too much. Quote Link to post Share on other sites
John McCormack Posted August 15, 2019 Author Report Share Posted August 15, 2019 Thanks all. Gearbox out next week to fix the overdrive. I'll take the pump off and see if I can follow one of the ideas above. Quote Link to post Share on other sites
