[Vwdiesel] '00 Golf IP pump seal problem

[Stephen Sherman]

Thanks for the input.

I don't think it is a fuel line leak, only because I don't see any fuel 
leak spots under or on the lines. And the fuel mist which ends up 
covering the IP and surrounding area doesn't point to a line leak (I 
don't think).

Could be a filter I suppose. This one is only 5k miles old, and have 
been running petro diesel for this time, so seems a bit too soon for it 
to be clogged.  I'll do a quick check trying to pull fuel from the 
filter directly and see if that happens.

Doubt it's glow plugs.  Just checked them a few weeks ago and it's been 
in the 80's (F) here. Warm enough that it should start just fine even 
without the GPs. (and the GPs would not likely cause an empty clear fuel 
line).

Could be leaking on the IP input shaft seal. I'll check it again, but 
last I looked the TB area was clean, no fuel mist in there. I would 
think that if that seal was leaking, then there would be fuel there.

If the filter is passing fuel, think I'll try the priming the pump 
through the return line and see if that helps, temporarily at least...
