Thinking this is factree. Finally the bed at 278k in my 2000 Excursion. I haven't owned it for the entirety of its life so I suppose it could've been changed at some point with a pump manufactured in 99, but what are the odds of that?
Figured I'd update on the Excursion since my fox is running pretty good and haven't done anything but wear down tires lately.
Swapped leaf springs from spongy, clapped out stock springs. X code springs on front, and what they call a modded B code on rear. Modded B is a C code, f250 rear spring, with bottom 2 leafs from stock pack added. Turned out amazing and rides and drives like a new truck. Couldn't be more happy. Waiting on my new tires to wrap my weld off road wheels in. Gonna be sweet......
I think your calculations are correct. The rear springs were terrible. I measured from the rear bump stop to my block before and after. 2.5" before. 5⅞" after. The rear springs, before the added leaves, were rated at 1400 pounds more per side then stock. With the added leaves I'm not sure of capacity.
My 4Runner sending unit kicked the bucket last year at around 255k so I replaced the pump with a new OEM one. Didn’t have any issues just figured while the tank was down. I’m sure that pump woulda kept on kickin tho.
Had an 2006 Grand Prix GT 3.8 SC. Threw a rod at 298K miles. Still had: Original alternator, power steering pump, fuel pump, AC blew cold AND TRANS shifted good. Car was in great shape, EXCEPT THE BIG HOLE IN BLOCK.
As a side note, Foxes were always good to me RELIABLE.
