Thanks for the info. So far I am still waiting on the vacuum fuel pump to get here. Does the vacuum pump mount exactly the same as the electric pump? I had to replace the front intake anyway since the old one was leaking at the mating surface with the cylinder. Since they did away with the electric pumps all intakes are now with the vacuum connection. If need be I will order the rear intake as well, I don't get much faster than 55 mph anyway on my drive so I hope this will finally end my issues and I can get back to saving on gas money! But now I am curious about my old electric pump and wonder if it is repairable.
The electric pump is originally mounted at the outer rim om the left frame. Remove the screws and leave the holes empty. Remove the pump-relay (it is located right of the old pump location and you will see two holes that will exactly fit the vacuum-pump mounting holes.) The new pump must not be installed at the old position but at the former relay-position. Don't try to use the old screws of the electric pump to mount the new one. The size of the thread is the same but the heads are to big and thightening the screws will bend the vacuum-pump and it will leak.
I'll try to add pics of my installation after this weekend.
I'm not sure about the rules of posting pics from and links to other websites here. But to prove that there is a repair kit for the pump - look at the image below or

For successfull repair you only need to loosen the screw of the bottom cap of the pump, remove it and replace the old electric part with the new one. No soldering or special electrician-knowledge is required. You can solder a cable but crimping it will have the same effect. In most cases the contacts are burnt and melted or there is water in the assembly and its full of rust. To prevent the water-ingress into the pump, try to seal the "connecting line" of the pumps body with the cup with self sealing tape. To avoid burning the contacts look for a modified repair kit with "spark extinguisher". (It contains a little capacitor.) A detailed video is available at the dealers website.
All tips and instructions are for the carbureted model only. Not for the fuel-injected.
Btw: Why not only change the defective O-ring of the old intake and repair the pump if possible. This would be much less work to do and saves the bucks in your wallet...
