Fuel Pump Wiring Harness
 
1 Attachment(s)
The electrical connection between the yellow socket and 3 wire black plug tends to jiggle loose and cause the engine to die. I currently use my daughters hair tie to keep the parts together. However, the connection is still not the best and needs to be re-plugged every now & then. My question is: Where can I buy a new 3 wire black connector? or is it possible to bend the internal sockets in the black plug to get a better connection? Any info is appreciated.Attachment 81596

I have exactly the same problem with my boat. I tried using tie wraps, wire, elastics and tape trying to get it to hold in place but it would still cut out atleast once every time we took the boat out. I found that it wasn't the connector not being pushed in far enough, it was the actual pins inside the connector. I pulled it apart and bent things to make better contact and its been good so far. It hasn't happened in the last 15 hours i put on the boat so i think i have the issue solved. Once i park the boat for the winter i'm going to pull out the connector and find a replacement just to make sure the problem doesnt happen again.

Mine is doing the same thing as well. Drives me crazy.

To confirm, did you bend things inside the black connector? I'm thinking that would be easiest.

Ya i pushed the sockets out of the black connector and then i adjusted them so they grip the pins inside the yellow end on the fuel pump a little tighter. I adjusted all three wires but i know it was just the green wire that was giving me trouble. Its working for now, but i really should just replace the connector, as i think it'll loosen up again over time.

Its funny, the previous owner must have had this problem as well and misdiagnosed it. The boat has a brand new fuel pump, and all the wiring to the pump is new except he reused the last 6 inches of the harness and the old connector.

Find a schematic for the pump- I'm not sure the green wire has anything to do with how/if the pump will work.

Is it just the way the photo looks, or is the yellow plastic broken off or worn, where the black retainer clip slides over? It looks like it may allow the black housing to slide backward.

How many times has the harness been removed from the pump?

That should be a Packard connector. The only thing that could be considered a problem is that the terminals (the metal clips) will need to be installed using the proper crimper if you only replace them or the black plastic part. Del City may have them. If you buy a repair harness, use Heat N Seal splices with low temperature solder, not just regular butt connectors.

The yellow connector is new. I also misdiagnosed the problem and bought a new fuel assembly. (could not find an exact replacement for the fuel pump itself). The problem is with the black retainer clip. it's bent backwards and will not hold onto the yellow part.

I'm gonna give this a bump to see if anyone has a wiring diagram for this. Prob be useful in the future and i'd like to know for sure what each wire does.

any insight on how to get the terminals out of the connector?

I have the exact same issue on my '01 209. Only took me a year to figure out and to fix temporarily but annoying as all get for the skier that is waiting on the platform.

They need special tools. Not that something can't be improvised, but it risks damaging the terminal or retainer. If you have a T pin or something heavier than a stick pin, you should be able to close the female terminal enough to make better contact. If the retainer is damaged, this won't matter- it should be replaced. These are probably Packard connectors.
