My only concern with the mechanical is they fail into the crankcase right? My pops had it happen while running b100 and it was a mess to say the least. I got a bosch overflow valve from my local Diesel shop. Thinking about going with a Fass 125gph 0-75lb adustable.

they rarely fail like that .. chances of it happening like that are more common if your running like 4K rpm or more .. then yes .. electric only .. I regularly run mine into 3200 RPM and have no issues .. my old one was stock(209K).

go mechanical until you get it running good .. then take the time to set up the electric pump and such ... the mechanical will get u goin right now easily :tu:

So i cranked down the adjustment on my raptor and its now pushing 25lb (all the bosch OFV allows for) and then i cracked the injectors and pushed some fuel through. Still wouldnt fire. I disconnected my heater grid and gave it a little hit of ether. Started just like before. Still running rough and falls off below 1k. Thinking timing? You can hear in the video it sounds like a F'in machine gun at lower rpms. Im gonna try timing it. Any thoughts?

NO sound ? what am I supposed to hear ?

just check the timing... I would bet that's one issue ... if that isn't an issue .. start pullin injectors, you may have a tip that's missing or something..:humm:

Yeah the video isnt very loud, It misses at the lower rpm and sounds better up high. Still falls off idle too. Im looking for someone who sells a timing clock kit and im gonna start pulling injectors. Im also going to drain the bio from my tank and go get some real Diesel :tu: . I'll take pics when I pull the injectors apart and get em up here. At this point i wont be suprised if the bio has them all gummed up. :nope:

Got all my injectors pulled out and they sure looked pretty gunky. I stripped them all apart and let the nozzles sit in carb cleaner for a few days. Im going to blow through the nozzles with the compressor and then put them back together. Then Im taking them out to Diamond Diesel to get tested. Hopefully they work alright after this and ill get her back up and running :tu: .

Anyone know what the nozzle torque spec is??

Filling the fuel filters with ATF .. or SEAFOAM .. would have cleaned them up real nice..
but now that u have them out ..

Yeah I sure couldve gone with that first but I cleaned them and got them tested today. 2 were totally shot just pissing a stream :td: and the other 4 were popping around 240 bar. So I couldve got the 4 rebuilt for 40 a piece and the other 2 I couldve got new bosch ones for 95 a piece at my local shop. That was seeming real spendy though so I just ordered a set of 100hp DAP injectors for $375. :c:
