So: I don't know why that little finger pump doesn't work. And also, I'm inclined to believe that on my engine I don't really have to worry about loosening the injectors.
Anybody have any thoughts on this? And an additional question: if I were doing this properly, would I always have to remove both injectors (two cylinders), or would just one be ok?
Final question! prior to getting to the secondary filter, I tried opening the valve at the bottom of my Raccor primary (it's an old one: think it says model 2010. Has the glass bowl attached to a housing, with the filter inside the housing) and nothing really came out except a few drops. So then I unscrewed the top of the filter cap, and it came rushing out. Is that normal: is there a vacuum in there that prohibits the flow?
Thanks for any thoughts.
1) The finger pump works when all goes well
- which it does most of the time. But in any case it is always a pain in the... index finger.
2) No only loosen
one fuel connector on the injector farthest from the secondary fuel filter (on the engine). Don't remove it, we don't want to get any grit or dirt in that. Just loosen it on the threads a turn or so. That way the air can blow by and the whole fuel system gets bled.
3) Let the engine starter do the work when you give up on the finger pump. Often if the engine has stopped with the lobe not positioned properly, then the finger pump will be doing absolutely nothing - you could pump it all day.
4) With only 1 cylinder "off-line" the engine will try to start as it is cranked. A 4 or more cylinder engine will start and hobble along on its working cylinders. Holding the wrench on the fuel connector nut, pull it snug after the engine has forced out its air. This is usually a 2 person job. The engine will then start. Careful what you touch with the wrench. It can be easy to short the 12V causing a startling (usually harmless) spark.
Most people would apply common sense with this technique and NOT run their starter battery dead, or crank the starter motor so long that they fill the exhaust elbow and flood the engine and it is always good to avoid the spinning stuff on the front of the engine, hopefully you've read this far...
5) I have the same Racor: if you opened the water bleed screw (bottom) (while the engine was off) you probably need to loosen the cap on top of the unit to get fuel (and water if any) to flow out the bottom.
