i was doing the interior in my 1998 chanelled mini truck and called summit to order a full set of autometer carbon faced gauges. well i got my gauges and was hooking up the fuel gauge and it was not reading right. it said i had 3/4 tank and when i and i know the tank was on e. but anyway i called summit and he had never hurd of that prob, before but he would check on it. well to make a long story short the gauge was the wrong ohm rating for my sending unit. the guy at summit had them build me a custom guage using a ohm rating that was reversed from mine but they used the sweeping action of a cobra gauge and had it shipped to me with in a week and didnt charge me for anything. now to me thats customer service. gota love them for that.
