Greeting ladies and gents!
I have a stock 1600 engine w/generator on the Thing I bought a few weeks ago. The PO replaced the original stock engine back in 1990, the SN plate riveted in place of the original SN area is strange 5545 AD- 451691. The engine bay needs cleaning overall - a lot of build up of dirt, oil etc looking "wet" around my fuel pump and used carb cleaner to dissolve all that debris. I see what looks like 92 (manuf year?) in a circle molded on the side of the pump when you are looking straight at it near the base by the pin.

Now that it's cleaned off, I can see a little fuel starting to seep from under the top cover from the distributor side. My questions are 1. should I get a rebuild kit for the leaking fuel pump or order a new pump? 2. I plan to do an Alternator conversion so do I need to also change the fuel pump to an alternator model? 3. replace the fuel pump push rod for preventive maintenance if I replace the pump?

I have a new fuel pump stand and gaskets that I was going to change, but will hold off putting those in until I figure out the pump issue.

Thanks in advance!

My 2 cents, any time I question the operational integrity of any part on any of my vehicles, I change them. I changed my fuel pump last year, I don't remember how much, but I don't think it was much. Always worth the piece of mind to me.

Changed mine to alternator and had no problem keeping the generator style fuel pump.

Thank your for the replies, I think that since it's at least a 23 year old part, I might as well replace it as a unit. I'll check the condition of the fuel push rod and if it looks unserviceable, I'll order a new one at the same time as the fuel pump.
