I've just picked up a boat for renovation and it's got the GM 6.2L V8. Basically a good engine let down by the conversion, having said that, the conversion on this one is OK. I don't have a manual and have been unable to find any obvious way to bleed the injector pump. I wonder if it is some sort of self bleeding system or if the bleed nipples are just well hidden.
I've disconnected all the injectors and they are showing a weak spray. So can anyone help with either bleed location or how the system works.
Thanks,
 
I had 2 of them in a boat. Noisy thats for sure!! Had a few problems so it was a steep learning curve but ended being pretty good lumps all in all and parts are dead cheap. Midlands American are good for parts.

I had to changed the fuel pump on one (Stanadyne if I remember). I unplugged the wire on the top of the pump so the engine wouldnt fire and turned it over, cracking off each fuel line at the injectors . Mine was a mechanical lift pump so no other way I could think of really. Worked fine. Bit lumpy at first but within 30 seconds running sweet.

The mechanical lift pumps are also a weak point on these as they run of a cam and the push rod wears. Few tho of it and the pressures drop. Took me ages to solve it!!

Best of luck :)
 
Thanks for the replies. It appears that the system is self bleeding.
Just need to get a bigger battery!!!
Thanks also for the Midlands spares source.
Hopefully they'll be able to supply a manual.
Thanks again.
 
as stated before all pipes will need removing from injectors and then crank until you remove air from pipe.will probably only see dribbles coming out.refit back to injectors and crank again and should fire straight up.filling filters up with fresh diesel before installing can save a lot of heartache.most pumps cannot compress air to the same pressure as a liquid ie diesel and it needs this pressure to crack the injectors open via timed pump.may get a little spillage whilst rolling engine over initially but can be cleaned up after connecting pipes to the injectors and before firing engine up.
 
Yup, Just put power to the pump, opened the injector pipes and spun the engine, once no air showing tightened injector pipes and off it went. Since had a full rebuild although pretty good condition inside and discovered it was a 6.5 with a lot more power. Not been afloat yet so all the doom and gloom merchants can keep smiling!
