2002 newell air dryer

[encantotom]

hi all, today was at the bus shop and we looked for leaks while up on the lift.

i have 2 valves leaking at the rear for the tag axle breaks which i will get and have replace. the air dryer is also leaking out the bottom of the assembly. my bus mechanic said it was a wabco systemsaver 2000 but i cant find that anywhere. i tried to get the numbers off the casting but they are too small for me to read. lots of road grime on it.

i likely need to get a new one. anyone know what model this one is?

pictures below.

thanks

tom
