You won't get any argument from me about which one is best. It's not the one I have!
I would like to go to a cable throttle. The slide system is a PITA.
As for the engine location, that may be because of the size of the 637, the GVRW of 32,000 # and the aerial ladder.
Fuel pump is mounted on the top front of the engine with the 10"+ arm pointed down.
Now for a question for you and Mike.
The input drive shaft spline, to the pump transfer case has only about 3/4 inch engagement and is worn bad.
It looks to be designed that way.
I get bad vibration at 45 MPH. Top speed is about 55 downhill.
How much spline engagement do your trucks have?
