My pump is still holding up fine. The pump on my brute spikes at 8psi when the needles stop flow. I have had a couple of times where it overflowed gas out the vent tube if I was stopped on the side of a hill. I have lived with it because it runs so well and it has only happened a couple times in a year. I just bought one for a friend's brute and it only spikes at 4psi. I will be checking the pressure on these pumps before installing from now on. I will also be replacing mine with one that is set at a lower pressure. If anyone knows of a way to adjust the pressure on the 42s pump, I would appreciate the info.
