Well..

I'm an old Datsun person and I remembered that all of them I ever owned (1971 - 1969) including my Pickup and Roadster had access holes to reach the fuel sending unit. I dug around and sure enouh right in the trunk is an access hole.

Using solvent and a hand held hammer it type impact I broke the phillips screws loose. Removed them and peered thru the access hole.. hmmmm. Not good. Very rusty. Not confident that if wont break a bolt or something as I try to remove the small ones that hold the fuel sending unit to the tank. Or I could end up tearing the rubber (or whatever) gasket between the sending unit and the tank and be really screwed. I dont have any silicon at the moment. Maybe it was just a bad vibe thing. Cheapo Auto parts is just down the road so I could easly go get some silicon, but it still did not just feel like it was the right thing to do.

I sprayed everthing with screw loose solvent and replaced the Nissan hose clamps with American clamps on both the small and large hoses. (large I assume to be suction side. and small the return side. ) I kranked these down real tight. Before the hoses could rotate on their tube. Now they cant.

If I have to go this step least they will have soaked for a while in the solvent.

I fooled with glass prefilter and realized it is holding some air in itself I wiggled this around and got the bubles to line up with the exit port and got them out of there while the car was running. I then played with the priming pump again and I got no more bubbles bouncing around in the glass filter. Maybe now I'll be better able to diagnose things with this pocket of air gone. Esp. if a new pocket forms.

I did drain and strain what was in the cylonic filter. I got a twig looking thing and some other tiny junk out of it. Since the glass filter is still clean as a whistle the cyclonic must be doing a lot cause nothing but fuel seems so be going past it. Or is that just me convincing myself that that part of my work was not in vain?
