Help with a fuel pump issue Options

[pgeorgeson]

I just bought a 1974 2.0 and am having a fuel delivery issue.

I am not getting any output from my fuel pump. There is fuel supply to the pump (into the S port) from the tank and through the filter. I removed the output line ("D" port -- the middle one) and attached a test line feeding the test line into a bottle. When the pump runs, I am not getting any fuel out of my test line from the D port. I can hear it going "pssst, pssst, pssst," but no fuel ever comes out.

In addition, although it isn't sending fuel out of the D port, it seems to be pumping fuel into the return line. The reason I can tell this is that when I removed all the lines from the pump, fuel drained out of the return line where the return line attaches to the R port. After I did my test, I removed the all the lines again (to switch pumps) and quite a bit of fuel again came out of the R line again.

I have a spare pump that I got from the previous owner, and both appear to be doing exactly the same thing.

It seems like both pumps are pumping fuel into the R line instead of the D line. What is going on and how to I fix it or test it?

I took apart the pump and cleaned it and it started working. The car started and ran for about 15 minutes and then the fuse blew. After some help from others in another thread, I traced the fuse problem to the AAR, which was unplugged. I plugged in the AAR and the car ran again without blowing the fuse. But then after about 5 minutes it's died again. I checked the line from the tank to the pump and fuel is getting to the pump (after passing through the filter). I unplugged the "D" line from the pump and put a test line on it and now I am not getting any fuel pumped out of the pump again.

Therefore, I am now back to wherei started. Fuel pump is getting fuel and is running (I can hear it whirring), but is not pumping any fuel out.

I will take the pump off again, take it apart and clean it again, but I am worried I am just going to end up with the same problem. Before I buy a new pump ($$$$$) or switch to an alternate pump, any ideas of what I should do/check?
