Hi Don. Thanks for the reply (and, as I'm very tired and slow these days, I appreciate the simple answers!).
I changed the filter, started the motor, and then the hose started leaking/spewing fuel. I suppose that this could have been happening before I changed the filter (when the motor) was on, but I didn't check this. In any case, I replaced the short piece of hose, and now the fuel pump is quiet and the hose is not leaking. So, all is well. I am wondering if the pump was making noise because the hose was leaking rather than as a consequence of a clogged filter.
Thanks for the help.
David

Not trying to be a smart a** here but if your pump is 'whining louder' and that whining comes on after it (the pump) has run for a few seconds to build up the fuel pressure...and you have a leaky fuel hose at the connections from the pump to the filter only...you probably do have a clogged up filter. The pumps are designed to build substantial pressure..so yeah, it could force fuel past the clamps on the hose between a clogged filter and the pump outlet...
Get you a fresh filter before you bust that pump....The fuel filter change is normal maintenance on vehicles...Even if that is not the specific cause of your weeping hose and noisy pump...you won't be wasting the money for a filter swap.

Hi. I've had some experience with noisy fuel pumps and dirty fuel filters, but I haven't seen this before, and I'm seeking advice from those with more wisdom.

Actually it did start on the second or third try, and it idled just fine. However, after around 10 or 15 seconds, the fuel pump started to whine a lot louder than usual, and the whining seem to come on rather gradually (by which I mean over a few seconds rather than in an instant).

I then noticed that the exterior of the small (2 inch) hose between the outlet of the pump and inlet of the filter was completely damp with fuel and that small drops of fuel were forming around the clamps.

Might this happen all of a sudden (and possibly be related to the motor not being started for a few weeks? And, can a clogged filter cause the pump to push fuel through the hose clamps to the exterior of the hose (because the filter is so clogged "all of a sudden")? What else might cause this single little hose to be soaked in fuel (i.e., everything else is dry)?
