So, I tracked down everything that could be a potential place that could let air into the fuel system and found - the damn plastic tube that goes from the filter housing to a vacuum gauge on the dash had somehow come loose from the back of the gauge.... At least now I know what that gauge is for(if it starts pulling high vacuum - time to replace the filter) and now I know where the other fuel filter is...
Thanks for the help....
On a side note anyone know the belt size for the alternator belts? Might as well replace them while I've got the doghouse off.....
The Isuzu no. is 1136711430. If I remember correctly this is for a matched pair. The Gates number is 1420. I run the Isuzu belts belts because the Gates matched pairs aren't matched very well.
To answer Mike's question in the next post, the vacuum gauge is sold as an accessory by Racor for their filters.
