fuel pump appears to be leaking. Is it a home project or should I shop it out. Have good mechanical skills but have never done one of these. Please help

There's nothing too complicated about it other than it's not easy to get at where it is...
Personally I'd have a strong inclination to simply cut the lines off the mechaincal pump and install a 4 psi electric pump closer to the tank... That would also be contingent on having a reliable electrical system with an alternator rather than the original generator.

You are correct about the eccentric on the front of the cam. But there is a push rod - slides in the timing cover between the eccentric and the pump.
Wouldn't hurt to leave it all in there if he did as Rod suggested and went to an electric pump.
Rod, why do you suggest the alternator? Should be plenty of amps in an old generator system to run a little fuel pump.

I despise those generators... I wouldn't want to rely on them to run anything 'necessary' on those tractors. First thing I do with Lucas gens is toss em... Every once and a while I take a fit and decide to find out why they don't work... then I toss them. They were the single biggest downfall of that entire series of tractors.

The guy is complaining about his fuel pump, not his charging system. A decent 12V fuel pump here is $65 minimum; repop mechanical pump is $42 and I have sold 12 of them without return or issue in the last 3 years. I get that you don't like generators, but your "fix" isn't practical unless the pump and charging system are both down. If you are worried about the generator supplying enough to run the electric pump, you should also be concerned with the low-rent gas ignition switch carrying the necessary current. Unless of course you need to add a relay as well. More cost & complexity.
Give me a new mechanical pump and a half to a full hour to swap it in and I can get on with my life.

Like I said in round one... if the electrics were adequate I'd be ~inclined~ to install an electric pump.
Either way it's not a big deal to me. One thing I am sure of... is that given enough time both the electric pump and the mechanical pump will fail again at some point. Just a personal preference that I'd rather slip two rubber lines over the hose barbs and attach a wire rather than grub around that front cover.

Bob, don't be afraid of trying to replace your fuel pump. I did one on my '68 3400 and it was pretty straightforward. Pump was about $35 on ebay. Clean area around pump, remove fuel lines, remove 2 bolts, stuff rag in hole then scrape away old gasket, replace pump, reattach lines. My new pump came with a new gasket. The fuel lines leaked at the fittings at first. I never have much luck with flare fittings... best of luck to you.
