TN 75 fuel pump leak?

[musselmark]

I noticed some fuel spurting
Out of a weep hole in what I assume is the lift pump
On my NH 2005 TN75DA. What is going on here, its about 2 steady light spurts every second. Thanks

The diaphragm has failed. Time for a new pump.

 

[musselmark]

Can you replace the diaphragm?

 

[RickB]

New Holland does not support parts for the pump. Yes, the pump is bolted together so theoretically the diaphragm can be changed if it can be sourced.

The kit is a available but my dealer told me they used to rebuild them but got away from doing it as they never had great success with it. I ended up buying the whole pump for 100 bucks.

There ya go, you had the answer before you asked the question. The difference is when a dealer rebuilds something like that the customers pay shop rate for the labor. If you do it on your bench you do not. I wouldn’t recommend rebuilding one at my job even if I knew where to source the kit. But if I had a tractor at home I would probably put a kit in it.
