I have a 26 foot terry mh with a 8.1 GM motor on a workhorse chassis. Previously I posted that I had a fuel line leak. However after replacing the fuel line I still have a leak where the hose attaches to the plastic finger comming off the top of the pump. Workhorse wants $400 plus shipping for a new pump. My questions are 1. Since the finger is plastic or PVC is there a simple fix/repair for the finger. 2. Is there a way to find a substitute pump for the workhorse pump that would not be as expensive. I can't see anything special about the workhorse pump.
Thanks

Sounds like your problem is more with the housing and not the electrical portion of the pump it's self. Several suppliers for the pump , provided the housing is in good shape. The elbow in question is under full pump pressure so I doubt that any patch would hold. Did Workhorse provide you with a part number when they quoted the price? Could be if you have the part number NAPA or Auto Zone could provide a cheaper alternative.

Thanks for the input, I'll check with a couple of auto part distributors tomorow . I didn't know they could get workhorse parts.
Thanks

I had the fuel pump go out on my 95 Fleetwood Pace Arrow and was able to get the pump through NAPA for about 125.00.My unit was on a Chevy P30 chassis so all I had to do was look for a 95 P30 chassis pump.You will probably find several different ones and different pressures ,my unit required the high pressure pump do to the overall length of the camper 36FT.This was not that hard a job to change out either only took a friend, some good jack stands and a motorcycle lift to lower the tank down,took about 4 hrs start to finish.Check at napa for the workhorse chassis and I am sure you can find a better deal.

I purchased a replacement pump at about half the price that workhorse wanted. I purchases it at Napa. I have run into a problem. On the old pump there are three nipples on top of the pump. (1) 5/16 and (2) 3/8 . On the new pump it has (2) 5/16 and (1) 3/8. Obviously one of my hoses won't work. I was at Napa today looking for an adaptor with no luck. If I start trying to get special order fuel lines I start approaching the cost of the workhorse pump. Any suggestions?

Have you talked to Napa, if it's not an exact fit then you have good reason to return it and question their cross reference.
Failing a return for the correct part, it would be important to identify the function of each fitting on both pump housings.
3/8 Should be , pump pressure to the engine on both.
5/16 on the original , should be the vent line to the emissions canister, and have the same function as one of the 2 on the replacement , but you need to know the correct fitting to hook to or you can put liquid fuel into the emissons cannister and ruin it.
The remaining fitting will be fuel return from the engine, and if you can't return the pump, things could get dicy here.
Are the lines on the M/H plastic ?
Can you post a picture of the fitting / elbows in question ?
