what is "high"? t-stats don't necessarily cause pressure changes.. at least not enough ta really notice unless ya concentrate on lookin' at tha gauge without blinkin'....excessive pressure is usually caused by a "restriction" of some type.....
"new" doesn't always mean "good" nowdays either...'specially with tha crap gas goin' 'round... not just tha corn gas either....for some reason, I've seen ona coupla other boards, this is happenin' with a lotta carb motors with some of tha "name mechanics" recommendin' pumpin' it at "every restart"...I've not experienced it myself.... but I use 'lectric pumps 90% of tha time......
