Temporarily put a rubber fuel hose on the line from the tank, after you
remove it from the fuel pump. Blow in the line - you should hear air
bubbles from the tank filler (post a helper to listen with the cap removed).
One four things will happen:
1. You'll get blue in the face from trying to blow into a blocked fuel line
or pickup, or
2. You'll blow like crazy with no result for a few seconds, and then
there'll be a "phooomp" from the tank, because you have dislodged the
blockage (temporarily), or
3. You'll hear the bubbles right away, or
4. You'll feel no resistance to blowing at all, and hear no bubbles,
because your gas supply is not covering the fuel outlet pipe, either because
you have less gas than you thought, or because the pickup pipe has eroded
away and isn't fluid tight to the bottom of the tank.
Either way, you know the problem. If you hear the bubbles, you know the
fuel supply is OK, and your problem must be the fuel pump.
These are tricky to change on the 440, be sure to read in the IML archives
regarding dealing with the push rod.
