Bendix Footvalve

I was getting a E6 footpedal for my peterbilt at the dealer. I was given 286171N , i had a schematic which had a differnt part number. That part number pulls up a bendix footvalve with high temp rated seals. 5019317 - supersedes to 802911

Anyone know if theres anything different than the seals? And which is the one to put on (the high temp one.. lol)

 

Going to be swapping the transmission out, thought its a good time to replace it as its original.. although I am wary of these new cheap built parts.

 

Yes, correct. Just wanted some insight if anyone has knowledge on these.
