Thanks 30_40, NTFDAY, rspears, Stovens. rspears The reason I am not going with the stock mechanical pump is I grew up out here and have had lots of experience with the heat out here and vapor locking mechanical pumps. I figure that's why they went with a electric pump in the first place, the stock pump was probably vapor locking. Sounds like Stovens has had the same problems with vapor locking in Arizona too. I am only about a hour away from Death Valley where temps have reached 134 degrees before, yep officially the hottest place on the planet. This area I live in has lots of wide open area's with nothing around for a hundred miles or so in any direction. Not a place you want to break down in, Shoshone at hwy 178 & 127 is about a half hour from where I live, That's also where Charles Manson like to hide out in caves. Since people know he hid there , they think they can hide there too. If they want to hide they probably are not good people. Breaking down is not a option out here, Nothing for miles, high heat no one around for mile and when someone does pull over are you gonna want to chance it, if they are good or not??? Yep if you grew up out here you know about mechanical pumps and vapor locking. Why chance it. Kurt
