I recently purchased a LW-6 backhoe for my Jinma 284 and need to connect it to a Jinma hydraulic pump. Unfortunately when I received the backhoe the hydraulic feed line connector from the pump to the backhoe was not the correct size and the supplier doesn’t carry the correct fitting to convert it (see attached photo). I did a search and found several topics on this issue but seeing how some of the post were more than a year old I’m hopping someone has found the correct fitting to connect what appears to be 27x1.5 Female to18x1.5 Male. Any Ideas where I can find the correct fitting would be greatly appreciated.

I would strongly suggest that you remove those crappy metric o-ring fittings from the pump and convert it to SAE.
If you want to do it right you will have to take some risk here.
1. Remove the bolt on metric o-ring flat face flanges from the pump.
2. Disassemble the pump make clear notes as to EXACTLY how EVERY piece goes together.
3. Drill & Tap the existing suction & pressure port holes to 1/2" NPT (If you don't have a drill press and the tap here is your excuse to buy one - or take it to a pipe shop and have them do it for you.
4. Re-assemble the pump.
5. Convert your BH hoses to SAE fittings. DIY or hydraulic shop.
6. Install ½” hydraulic swivel fittings on the Pump.
I have done this on the standard pump located on the engine and it works great – no more leaks and I can use SAE fittings.

im not sure what you are missing? the ends of the hose or the bittings that are bolted onto the pump?
for a fix like described above you could actually weld on an adaptor to the 2 bolt o-ring flanges. then have the std NPT or flared fittings...
