I look for parts number to purchase on a website

for my 1993 f350
this heating hose has three pipes
and this probe on the turbo

thank's for yr help

 

I would find

this boost gauge kit

 

For the heater hose you can cut the crimped clamps off and reuse the T and regular hose clamps. I'm not sure what you are asking for on the turbo.

 

Photo # 1 the cheap fix is to buy a " Tee" and 3 clamps. Cut the old one out and put the new one in. You should be able to get that local.

Photo # 2 is the oil pressure sending unit( switch)

Photo #3 If that is oil in the plastic line, then it is oil sending unit with a mechanical gague added.
