Groco Oil Pump Hose Fitting

Have a Groco reverso pump system and while completing oil service yesterday the plastic hose fitting that threads onto the outlet/inlet of the pump cracked guessing from age. Took to several places today to replace and can’t find replacement with the same thread. Being based in New Zealand we have different standard threads to you guys. An engineer here thinks it’s a NPT thread at 3/4” which is very rare in this part of the world. It could be your typical garden hose fitting which will be different to ours.

Can anyone tell me what the thread is. I have reached out to Groco. Hopefully it’s a off the shelf fitting I can order from the States and have sent down under.

Upside, completed both engines and filters prior to it cracking. It was on the genset when it happened. First boat with a reverso type pump, what a godsend they are. Simple and fast procedure. Thanks.

That is a standard garden hose fitting here in the US. Look on Amazon, I am sure it will be available. https://www.amazon.com/PLG-Garden-R...4638645&sprefix=garden+hose+re,aps,982&sr=8-6

Ordered one today through Amazon. May be standard to you guys but unusual thread down here. Fingers crossed it fits.
