My 2015 GC1710 with DL95 has what appears to be 1/4" ISO 7241 - A series. Is this correct? IMG_20191001_203857.jpgIMG_20191001_203917.jpg

I got a 2018 model. Having myself ordered the wrong male connect on Kenny's prv gauge, here's what I could tell you, go take another look at those couplers for any markings. On mine, the male connects just have some numbers that lead to nowhere on a google search. The female connects are Safeway 545-3P. I called Safeway, was told the male connects which match those are ISO 5676 3/8", which is what I ordered on Amazon yesterday.

Finally got a chance to try out the gauge, got a reading of ~ 1900 psi, so guess it's fine.

I got my gage as well. I'm definitely showing some weakness in my system, which is fine, as it definitely isn't used as a lawn mower. I measured out at about 1730-1740 PSI. I figured I was getting weaker when I tried to lift something heavy I lifted a couple years ago that I could no longer lift as easily or highly. I'll have to fix that in the next few days before I start my next project of adding dual rear remotes.

That male coupler looks smaller than mine. Mine are 3/8". You may have the 1/4", here.

I would agree with you.

Pretty sure 2016+ they went with the larger couplers.

I have the 1/4” on my 2015. Curious if it would make much of a difference to flow rate changing them to 3/8” ? Must have been some reason Massey changed them to a larger size.

Mine is a 2015 and I can confirm I had 1/4" fittings. I would expect a smaller size means faster flow as the pump volume is the same regardless of fitting size.

Don’t wast your money.
