So I was commenting on how well the car was running last week. But the past few days I've driven it I noticed it was running rich...moreso than usual. And it was starting hard when hot. It's always suffered from that a little bit. And my FP numbers after shut down have usually dropped a little bit, but nothing to be alarmed about. Seemed intermittent, though. I have a new walbro pump last year, rebuilt injectors, new fuel pressure regulator diaphragm about 3 years ago, etc.

Anywho, after I drove it to the restaurant and post office today, it was an exceptionally long crank time to get it restarted...and reeked of a rich condition, like an old carb that was flooded.

So I pulled in the garage and left it running. Pulled off the FP regulator vacuum hose from the plenum...what to I get? Fuel dumping out on my finger. Damn it. Good in the sense that I know what the problem is. Should help with my mpg, too. Bad in the sense that now I need to order the part and pull the fricken plenum off to replace it. Ugh.

For future reference I was digging around -

Part numbers/cost are as follows:

AC Delco 2142156 / GM 19187371 - I've seen this from $69 to 180!
Standard Motor Products PR10 - From $45-$55 depending on site
TPIS has is on their website (part #15?) for $39.95

I'm not sure what I'm gonna order yet. I like AC Delco parts but that's a hard one to swallow. I might go with the TPIS version.

So...like I said, if it's not one thing, it's another....
