This.

Remote mount the pressure transducer off the engine --- vibration does a job on the service life. I used fittings and a about 3 feet of hydraulic hose and extended a ground wire and the hot wire to the transducer. It should last thousands of hours if remote mounted.

Well, just to finish this thread off - I installed the "gold plated" Westerbeke oil pressure sender unit and Bingo -a steady reading on the guage - yahoo.

Interestingly, the old one was quite heavy, suggesting it was full of oil. I intend to cut the old one to see how it works - perhaps it has some sort of bladder arrangement in there that expands with the oil pressure acting on a rheostat (or something) and that burst.

Thanks for your comments
