Nut and Bolt Your Race Car?

Very good advice, speaking from experience. My race car partner & I went to a NHRA national event in Dallas a few years back. I had been working out of town the two weeks before the race. He was supposed to go over our stock eliminator Dakota before I got back just in time to throw my bags in the trailer to head for Dallas. We get to the track, unloaded, go through tech, get everything set up for test & tune that evening. I asked, "did you go over the entire truck, bumper to bumper, door to door"? His reply was sure, I checked everything. First pass for T&T, I notice him outside the truck at the first turn out with the hood up & flapping his new race jacket at the engine compartment. I jump on our pit scooter with a fire extinguisher & race down there, by the time I got there the fire was out. But, the damage was done, wiring harnesses are toast, vacuum lines melted, hood blackened, & the cowl vent cover melted. I asked him what happened & he said as he went through the traps, gas started spraying everywhere & it went up in flames. The one thing he didn't check was the AN fittings on the fuel injection rails. We laugh about it now, but it really wasn't funny then because I spent most of that night & into the wee hours of the morning replacing wiring & vacuum hoses so we could run first round the next morning.
