Maybe lucky, it ain't runnin yet. Wish I'd known or looked into it more. I'm getting the oring that seals the back of the two bolt flange that the shutoff rod pivots in, but is there one inside there too? The arm is pressed on behind the nut, don't want to remove if not necessary. Feels like a...

So, if a guy is gonna fire one up that's been sitting, it would be wise to pop that plug out off the top of the HH and let some crud-breaker-upper soak in there a day or two first. I noticed carb cleaner dissolved the crud off my primary filter (brass wafers) pretty good, but it may damage...

Got HH off on my lunch break. Yup. Button fell off. If I had only....:roll::oops:aua:cookoo::mrgreen: Retainer plate isn't broken. 8-) Looks like the plunger should travel around .375". Mine is a little stiff in the upper end of it's vertical travel. Will investigate further after work. Is...

Yeah, well I feel like an idiot then. :oops: I like to think I'm smarter than the average bear, but obviously I should have just listened to you in the first place and gone straight for the button. aua I just wanted to understand how it all worked and make sure it wasn't something simpler first...

When I get this thing running, I will post a thread and maybe a video on troubleshooting the deuce fuel system to make it easier for the next guy. IP TM http://www.jatonkam35s.com/DeuceTechnicalManuals/TM9-2910-226-34.PDF

I hope that's all it is, makes sense. I wish I knew what full stroke was.

Tonight I disconnected the fuel injector return line and cranked it without the electric pump running. Got weak flow out of the HH but nothing out of the 1/4" inj return line. Cleaned the primary filter, which I should have done in the first place. It was dirty, but not horrible. I was getting...

Machine shop coolant sprayer siphoning gasoline instead of coolant. :cookoo:8-)

Gives me half a mind to put a flange on the intake tube and turn it into a draw though turbo carburetor setup, haha!

Don't try this at home! EDIT: If your Injection pump is not getting fuel, and you run the engine on an alternative fuel source like this, you will likely destroy your hydraulic head, because it is lubricated by fuel. Video of it running on "alternative fuel supply"...

I bypassed the regulator and filters completely and went straight to the HH, didn't run, but might be improving, smoke out the exhaust. I talked to a buddy last night and he pointed out a that I ought to do a flow/GPM test, not just a pressure test. I never have checked the inframe primary...

Well, I ran the high-pressure pump to the tee that used to be on the fuel density compensator and put a gauge on one leg of the tee and the other leg to the hydraulic head. Ran it on gas for a minute or two and it never caught. Gauge only read 40 psi from the electric pump, no more from the...

Old post about regulator valve : http://www.mil-veh.org/archives/06-06/0605.html

High pressure straight to the FDC, one injector line disconnected. Line gave regular little squirts while cranking, but pretty weak and no fire. Gonna try bypassing the FDC.

Thanks for the well wishes. Yeah I was up reading until the wee hours last night and last week, not to say I havent missed anything. I took the pressure regulator valve apart again and smoothed up the plunger and stretched the spring from an inch and 3/4 to 2 inches long and put it back...

I thought about bypassing the regulator and filters and going straight to the FDC or the HH, but that might be too much pressure...hmmm. Maybe it's as simple as the fuel filters are plugged up solid and so all the fuel or most of it is bypassing to the regulator valve and just returning to the tank.

Aha! I suspected the spring loaded pressure regulator valve (opened and cleaned it earlier) , so I dead- headed the high pressure pump to the gauge, cranked it with no elec pump and was rewarded with the gauge going all the way around past 60 to the pin at zero. Perhaps the regulator valve is...

Video uploading, I ran it on an artificial supply of air/gasoline into the turbo intake for a few minutes while I fiddled with the IP throttle and shutoff rod to no avail. Gauges = 60PSI of oil, tach about 1,000 RPM. No fuel pressure at filters unless electric pump is running. Thinking the high...
