Fuel Pump replacement

Don't go, Highwaymen. If you want your vehicle fixed and don't care what they charge, fine then go. If you don't want to get fleeced, then avoid this shop like the plague. My son recently had the unfortunate experience of breaking down in Cheyenne at 3:00 in the morning while traveling from Idaho to Missouri and being towed to this shop, were they gave him an estimate of $1000.00 to replace a fuel pump in a Tahoe. They charged him $400 for a 213.00 fuel pump and $120 for diagnostic. It does not take $120 to diagnose, "No Fuel pressure and that there is power to the fuel pump, and no you cant hear the pump running". When I had my kid challenge them on this, after I looked up the fuel pump on O'Riely's Auto Parts, they said that did not have one of those, they used Napa, and that it was standard practice for them to Upcharge on parts. Although I suppose, it might be standard practice for some auto shops to upcharge on parts, I have never been charged more for the parts than what it cost the shop to get them from the parts store. I guess it is reasonable for a small percentage of upcharge, especially if the shop is picking up the part. But in my experience, the parts store delivers parts to the shop. However 100% upcharge is not reasonable, nor is moral or ethical, and in fact is highway robbery. Their only saving grace, they did get him in 1st thing that morning and had him on the road late that afternoon, and when challenged on the cost, the did drop the prices from $1000 down to like, $929 or something. Oh, the tow truck driver that picked my kid up, told him because our Road Side service dispatched the pickup, his only choice was to tow to Big Al's. I am betting the tow belong to Big Al's. Short of this is, Big Al's Auto & Exhaust took advantage of a kid that was stranded in the middle of no where and he was stuck where the tow took. They figured they had him by the peanuts and he had no choice except to pay what they said. They are unethical, lacking in moral principle or character. No respectable business would operate in this manner.
