djmaguire: Thanks a bunch!!!! that's a lot of studying!!!...
Not trying to overload you. I'd just work with the description docs and only go to the long ones if needed.
...One thing I also not understand very well is how using the shredder valve cleans the low pressure side (of air) and the other side of the cooler cleans the high pressure side. Is that just because mechanically the bubbles from the high side all end up there and the ones from the low side end up in front (by shredder)? Because the cooler has no valve in it so it passes through and when you pull gas (and air if you're bleeding....) from either side, pressure should be identical right?
Even with no valve, the internal configuration could make a difference. If the fuel inlet and outlet - internally - are tubes that go to the lower part of the cooler, air could get trapped in there on one side ot the other that could only be released by letting it go at that particular connection. We tend to think as ports as ending at the enclosure. There could be a lot going on inside beyond even the passages.
Is the motor mounted filter housing a common failure? I agree that I might have an issue there. I did notice that not as much gas comes out of the high side than low side (fuel cooler) when I turn the pump on. Would the pressure valve in the filter housing malfunctioning cause that symptom?
Not sure about common. ...and can't say whether the difference is a symptom or not.
Edited to add...
I noticed that one of my PDFs didn't start on the correct page. Attaching the corrected version.
