All my pumps leak into the bilge under the pumps. I am tired of cleaning up the mess. I think that the reservoir or the caps on the reservoir are leaking.

Has anyone used the billet trim/tab reservoir made by GRP. They have billet caps and clear round Lexan reservoir body. Did they stop all the leaking mess?

I can't answer about GRP.

I did a cheap fix on my previous boat. I fabricated a couple of 12* blocks to go between the transom and the pump mounts. I think they leak because of the angle of most transoms. No more leaks!

With mine, it wasn't the caps leaking. It was where the reservoir meets the pump body.

Same here. Mine leak sitting still on the trailer. Not enough to find the leak - just weeping from the pump/reservoir body, I guess.

The platic reservoir split on the seam over time and leak , happend to my trim pump reservoirs ..

Billet reservoirs are on order, anodized red. For $600.00 I hope they don't leak.

What reservoirs did you order BAMA?
I'm considering replacing 3 of mine with the GRP style.
But from what it looks like, the volume of fluid is cut in half from the plastic ones that leak.

seen that many times.
