Just the round top that has the injector lines coming out of it.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
ANY fuel filtered or not is better for a HH than NONE. While my filters did need replacement (my fault), I was still getting fuel.starving a rotating element of lubrication is the correct summation methinks
then again one may use a last chance filter at 3 micron for the new equipment
doesn't matter the fuel... it must be filtered better for me

I can't agree more. All the suggestions and the documentation of your troubleshooting gives those of us with less experience a path to follow if trouble should arise. More importantly, the honest explanation of what you feel led to the trouble, fuel starvation at high RPM and continuing to drive, gives an important lesson in what not to do when you run out of fuel. Something I will certainly remember if my deuce starts stumbling on the road. (Better get that fuel guage working!)You've done a great service to everyone on this site documenting this issue. You have likely saved some people time and expense regarding the perils of running out of fuel and how it can damage the HH if the engine isn't shut down immediately.

In winter months I thin my WMO/UMO mixture with either old diesel or hydraulic fluid, usually 80/20. I also filter it down to 2 microns, haven't had any problems in cold weather except for batteries not wanting to cooperate when the temps drop below 40-degrees...just got a battery heater wrap for them.Just Remember the when you use use motor oil it is thicker than Diesel fuel and you should have it in another fuel tank so you can heat the used oil to at least to 150 dgrees bofore you switch it to primeary fuel for the engine can run on it like it should but you could run 50/50 and it should run fine
This is something I'm trying to do but the center plug is extremely tight and I've not been able to loosen it at all evenif you have good fuel pressure at the final filter that is all ok. you can flush the HH plunger by removing the center plug, turning engine so plunger is at lowest point, remove fuel supply line to HH, set throttle to max, and use clean air and fuel to push fuel and air down the plunger. this will dislodge any debris that may have blocked the plunger inlet. it may also show if any 'stuff' comes out the in port of the HH.
It takes a good bit of effort.This is something I'm trying to do but the center plug is extremely tight and I've not been able to loosen it at all even
after soaking in penetrating oil and far exceeding torque spec. Do you think this is an indication that something is amiss with the HH/IP or am I just too weak? Sure don't want to break anything more than it already is.
Thanks for your suggestions.

Tom,With #1 at TDC and the timing pointer on the IP lined up, turn the engine backwards exactly 120°. The HH should now come out, but do not apply force.
