Sort of a side issue, but somewhat related: I was at the mechanic a few days ago booking truck in for fuel pump replacement (240,000 km and I prefer scheduled maintenance to roadside breakdown). He mentions he's had a bad run with after market pumps for chev lately, 4 out of the last 6 failed within weeks of install. Hmm, I have 2 trips to the coast in the next few weeks. I had him call dealership and order Delco part. $250 extra but what price on disrupted WH charter while you get towed and repaired?
