The hose that comes out of the aftermarket FEL valve on my Yanmar YM2310 and goes to the fluid reservoir has a fitting with a very small hole. The hose is 1/4" I.D. but the hole in the fitting is only about 5/32" diameter. So the flow coming out of the valve is restricted. I checked the other hose fittings connected to the FEL valve and none of them have this constriction. The valve has a power beyond port that is plumbed to the 3PH. The only reason I can think of for the small hole in the fitting is to add some back pressure and that this back pressure maybe has something to do with the power beyond function. Is this correct?
Thanks,
Eric
