    odd problem, long ways from home.

    Yea, finally got around to changing the pump again on Saturday. Put in a new delco pump and delco FPR. Also changed the rear tranny seal while I was down there. All is well for the moment.

    odd problem, long ways from home.

    Could be the gauge, it's a Bosch I picked up at orileys. Got the intake off, only found a noticible clean spot under the fpr. New one installed. Truck runs better at idle and doesn't stumble as bad, but still throwing system rich codes.

    New here, 99 Yukon strange issue

    Thanks for the tip on the lower gaskets, forgot about those. Is the plenum breaking a fairly common issue? I've helped a couple friends replace their fuel spiders that were causing intake backfires, just never seen one shatter like that.

    New here, 99 Yukon strange issue

    So I've been searching through these forums for a week or so, and I haven't seen this particular issue. So here is some background info. 1999 Yukon slt, 200k on motor and 80k on trans. Maintained moderately well (new cap, rotor, wires, coil, plugs, air filter, fuel filter). So truck was...
