TL130 pump leak

After working on many electrical issues I’ve noticed the top of my hydro pump leaking.

I’ve been able to locate a complete pump rebuild kit, seems overkill for just a few gaskets at $190. Anyone know of a vendor for individual parts?

Is this a difficult repair? See attached pic.

I doubt the pump itself is leaking. One of the fittings or hoses is more than likely the culprit.

That ain't a pump leak. Those fittings need new Orings. They are BSPP, and, IIRC, I use a 1-1/4" wrench to tighten the jamb nut on my TL150 machines (and TB180FR machines).

There are 5 Tee fitting on top of hydrostat pump. They all use a 1420310912 Oring, which is specific for BSPP (British Standard Parallel Pipe). Use of a an SAE Oring instead will result in a leak.

Thanks heymccall! That is the exact info I was looking for. I ordered 5 of them and will hopefully fix the last issue for a while.
