Howdy,

I dunno, BUT, I think if you checked with Bosch....the might recommend filling the entire fuel side of the pump with diesel, as opposed to ATF, and also of note....the new ULSD is supposed to be less than 15ppm Sulphur.

Attach a hose to the priming pump, and pump it full....if you happen to have a spare banjo fitting.....plug it and secure it with the pump's "banjo bolt / pressure regulating bolt"......

Bear in mind that there is a lower end of the pump that is lubricated by the engine oiling system......I would flush with Kerosene or ULSD until all of the sooty Lube is cleaned out.....and refill with clean lube oil...personally I would choose SAE 30 Non-Detergent (air compressor oil)....but it probably would not make much difference.

See if you can find some cosmoline or a product LPS-V3.....if you have a Grainger near you...they will have something to paint on the outside.....if you happen to have some exrta fuel pipe nuts, screw them onto the pumping elements, to protect the threads.

Wrap in cheesecloth, and duct tape.....put it in the spot with the lowest relative humidity, that you are willing to keep it in.....

Just my thoughts......

SB
