So the impeller came off the shaft ? Was the impeller plastic ?

Could you take some pictures so we see how these things fail ?

 

Yeah we'll deff. take pics...Tho this didnt die as usuall but could be the cause to the death of them.... The motor still ran, it just had no where to cetch....

UPDATE!!!!THE TRUCK RUNS...IT is out on a test drive now....

Now to get him to buy a Fuel pressure gauge....

 

Thanks.

How did the other pumps die ? Electrical ?

 

The other pumps motor died...

 

That is why I guessed electrical. That is usually the problem with these pumps. The motors are too light for the load.

 

Same exact thing happened to my pump about two years ago.Was replaced under warranty.
The impeller rotor is pressed on the motor shaft using a plastic or nylon bushing. The bushing must deteriorate after while.

 

Ahh that makes sence, my dad couldnt figure out why yhe shaft wasnt connected, he thought that the bushing fell out when he opened it up, but deteriorateing makes sence....i guess it deteriates then spins freely and burns up....more to the mystery of the lift pump...

Is there a replacement for that bushing, our wekept the pump and the pump runs fine, just w/o that bushing it wont spin, so if we could geta replacement bushing we have a backup bushing

Mike

 

If I keep my old pump I would have made a bushing out of brass and press it back on.

 

Good Idea...Might have to do that, are you good with that kind of work? might send out the LP to you and have you make one up if its wasy enough

 

Well we got the pics of the Shaft and the Impeller on the Lp...Stay tuned for a thread on it..

 

I don't mean to highjack the thread, but I like this Walbro pump idea! I'm getting ready to do my VP and was going to do the LP at the same time (even though it's only got 10K on it). Has anyone with 2nd gen done this mod? I'd like some info on how to hook the system up (placement/type of regulator, etc.). I've got the Vulcan relocation kit installed. Would I have to upgrade the hose to the "fuel injection" type, since this pump is capable of hitting higher pressures?

 

I'll answer this in the Implementing a Walbro thread to keep it all together.
