Center MLS Ballast Pump

Recommended Posts

Has anyone installed a higher volume ballast pump on the center mls tank fill and drain ? The stock pump is undersized. If so what brand and model fits in the compartment ? Thanks..

I replaced the stock 700gph with a Rule 1100 gph.

Big difference.

But the outflow is a 1" id versus the 3/4" of the stock pump so you hafta adjust your plumbing.

What I did was a 1" id hose directly into a hi volume Y with 3/4" id outs and shutoffs.

Sent one leg of the Y to the MLS and for the other leg made an aux. to connect a hose for filling extra sacs that I may want in the cabin.

Also Mayfair makes a 1000 gph that has a 3/4" out. These are kewl cuz the motor is an easy to replace cartridge
