what do you guys use to step up a pump with 3/8 outlet and hose that's 3/4 inch ? :splitspin

Not totally sure what you're asking. My MJ1200 has a 1/2" outlet. I've stepped it up to 5/8th" by putting a 1 inch length of 1/2" tubing on the outlet. You can probably step it to 3/4" by using a short length of 5/8" in addition to the 1/2". A plastic hose clamp would make it more secure. With vinyl tubing the size convention is ID. OD is typically about 1/8 more.
