Anyone have one? It's a Ford Rotunda pop tester I bought a few years from Ebay that came with a Nozzle cleaning kit (made in the UK). The gauge was smashed in shipping and I replaced it with the 6" gauge. The aluminum base is a gallon sized reservoir so it is a stand alone unit which does not need mounting. I think it was a new unit since there was no signs of diesel or oil anywhere when I got it. It worked fine for 2 years and then one day I could not get it to prime and push fuel into the injectors. I tried everything, including filling the high pressure pump plunger cylinder with fuel, to no avail. Finally ditched the reservoir (which constantly leaked diesel past the cover's cork gasket), and gravity fed it with a water bottle via a filter. I had to take the handle off to quickly cycle the plunger to finally get it to prime. I am going to leave an injector mounted when not in use to avoid losing prime again. Maybe I should have done that from the beginning?
This shim kit came in handy. The last set of Monark nozzles I installed went in without changing any of the shims and pop pressures were perfect on all 5 injector bodies. Not so with this set. I am not sure if it is this set of Monarks or this set of injector bodies (bought from Charmalu). I had to change shims(to higher thicknesses) 2 to 3 times to get all 5 set to 2100 psi.
This is the way I test the injector body halves for leak, shaving cream! I did not lap the injectors with grinding compound or sandpaper like a lot of online instructions recommend. If the injector body was not leaking, why lap them? All I did was rub them on a piece of paper with solvent to burnish off the dirt then blow off the lint and clean with solvent.
Painted them with POR-15 to keep the rust in check. I am hoping they will run well and get me better MPG. We shall see.
