Hey Paul, I was waiting for a response from you. [img]<<GRAEMLIN_URL>>/grin.gif[/img]
Nope, no return line. Just the single 3/8 feed line. Now, coming from the tank on the passenger side, next to the feed line, there is a second line that disappears under the car somewhere, and there is a line connecting to the charcoal (?) vacuum canister at the front of the engine bay. I assume it is the same line.
There are also 2 more lines connected to 2 more ports on the same side of the tank but don't have clamps, and running to unknown locations, and also 2 more old lines (not connected to the tank any more) going up into the trunk body area from the drivers side of the tank that don't have clamps, so I assume they are vents or breathers, but there is no canister apparatus in the trunk, and I have no idea where they end up.
This is getting confusing, and I keep editing here- in total there is a feed line, a vent/canister line to the front, 2 more unknown lines that are connected near the feed and canister lines, but they don't have clamps, and 2 old lines on the other side no longer in use, with only one capped port on that side of the tank. WHY on Earth would there be 6 lines???
This car ran great until yesterday when the issue began. We have gone through the entire fuel system at this point. There are a couple of sections of fuel hose, and I replaced them with new fuel line and hose clamps, to rule out dry rotted line sucking air (which is really the best way to describe the symptom.
Under any driving condition, both filters would eventually run almost dry. Obviously it would occur faster when getting on it. Now I did just change a section of hose I missed earlier, and put a new piece on the canister portion under the hood, and went ahead and clamped it since it fit a little loose.
ON a test run I just took, it seemed to not run the filters dry, and even made a hard run through the gears with no muss this time. But it still drops from it's usual 9 psi down to anywhere between 3-6 at times, not just when getting on it either. ** (This is also just a POS standard mechanical pump used in an emergency situation at the time.)
I can't explain why it worked fine before and has these problems now, and I can't imagine anything getting past the filter element into the carb.
I am definitely going to get a nice MagnaFlow electric pump/filter assembly as soon as funding allows. I would have to think that pumping fuel from the rear is much better than trying to suck it all the way from the front.
Any thoughts on the possibility of running a new hard line the whole length to do away with the hose sections? It seems there is going to be at least one section in there coming from the tank sending unit to the pump.
Any thoughts or help would be great.
Thanks everyone, and all your input is very welcome and used. Once I get through this issue, I will do away with the glass filter. But for now it is valuable for debris confirmation.
Here is a drawing to either help clarify, or totally confuse you. [img]<<GRAEMLIN_URL>>/grin.gif[/img]
