Reefer 250 G2 return plumbing

[aggrofish]

So I’ve searched and I‘m still confused. I recently picked up a reefer 250G2 and have a vectra s2 return pump. The pump output side is 1” and can be reduced to 3/4” with a barb. The return pipe plumbing is 25mm with a nipple reduced down to I believe 17mm, maybe 1/2“. What I’m trying to do is find out what part I need to change the return pipe fitting to 3/4” to make for an easy connection.

on My 350 is a cluster you know what. I have the same S2 with 3/4” tubing and a reducer fitted to a smaller return hose. I’m trying to avoid that. Appreciate any help.

You can simply unscrew the included hose barb and then screw in any fitting that is 3/4in MPT with some Teflon tape.
