    Hi. Does anyone know what the 2 round black fittings are as shown on the photo? Next to fuel filter plug. Can they be loosened and fastened again? One of them is leaking diesel so I want to tighten it but scared I break it.... Any other thoughts? Thanks

    Looking at the hex on top it COULD be used for loosening/tightening although the edge of the tank does not appear to have a thread.
    My advice, take the picture to the nearest GM dealer mechanic and ask him for advice. Only the trip to the dealer would cost money.

    Thanks Harry. As per your suggestion I sent a photo to the dealer. Could however not wait... and fastened it. Luckily nothing broke and leak has stopped!

    As a matter of interest Brent, who does the servicing on your Trailblazer?

    The leak should have been sorted by the dealer as your Trailblazer should still be under warranty.

    Hi Malcolmj. I am a long standing client of Perderberg Motors Malmesbury. Yes I could have taken it in but my personality is such that I like to first try myself :-)

    Good for you on doing things yourself. I use to be that handy also untill I got lazy. Keep in mind that you do stand a chance of "damaging" your GM warranty when working on the vehicle yourself, howeeeevveeeerr, I will keep in mind this issue and your solution should my lorry give the same problem. Thanks.
