Go to your local VP dealer with your SN, they can get them for you. You need 3 for the engine, 1 for the drive

Re: Electric Fuel Pump Runs Continuously

I installed the alternator but now the fuel pump runs only when the ignition is in the start position. The engine runs for about a minute, bogs down and dies as if out of gas. I noticed that the pump does not run when the iginition switch is in the run position. I tested for current in the run postion and got nothing however I did get a reading when momentarily turning the engine over. I checked the fuel pump fuse (7.5) and any other fuse I could find and reset the circuit breaker and it still has no power in the run position. Not sure what to check next.

Sure you got the right alternator, and have it wired correctly?
When it starts, the alternater should show voltage on the green wire, does it?

No but it had a VP sticker and it is a Valeo. The outfit deals with Marine alternators but that really doesn't mean anything.

No voltage on green however I did get it on the purple. The engine runs for only seconds now so I'm wondering if the fuel pump is even working despite getting voltage in the start position.

You still have alternator problems.

I jumped the fuel pump and the engine runs great! Still no voltage to the green wire and the choke still gets hot. I will be returning the alternator despite the shops statement that the alternator is OK. I also note that the battery had only 4volts so I wonder if the alternator had drained the battery. Good thing I had a new battery.

Replaced the rebuilt alternator with a brand new one and it runs great although the choke still gets hot. I have temprarily disconnected the hot wire until I pick up a new choke.

It's normal for the choke to get hot, that's what makes it work!
