Fuel pump was replaced to cure a surge I was getting. Testing fuel pressure showed sudden drops in pressure, and when we dead-headed the line it took ages for the pressure to rise, going up in stages from 45psi to 55, then to 65, then to 70, then to 80. Curiously, after that, pressure would jump immediately as you'd expect when the line was dead-headed. And the surge disappeared at the same time. I suspect a stuck pressure valve in the fuel pump bleeding off pressure. Given what I found, replacing the fuel pump seemed the logical move. The sensor took care of my temp reading issue, and the water pump went on painlessly. Need to check and see if I've already fixed the airbox flap to fresh air. Think I did that years ago, but never wrote it down.
