I'm having the hardest time ID vacuum hoses and replacing them. please see picture, I have no clue whats its connected to? also, please let me know if I connected the purge valve correctly? Is one end suppose to connect to the nipple off the oil fill tube? I can't seem to find an easy to read diagram, I have the FSM as well. Also I purchased about 12ft of 5/32 hoses, what other sizes and length would I need? Any suggestions on where I can find cheap silicone hoses?

 

You may want to explain to the forum the year and model, do you self a favor don't bother buying cheap vacuum hose you don't need any leaks and quality hose is not anymore expensive any way. IIRC the '91 T2 requires 13 feet of 3.5 mm and 6 feet of 6 mm

 

Profile shows '87 NA, pics. agree (but it's always nice to put this info in the post).

Maybe this helps:

Mazdatrix shows those numbers to be good for all years 86-92

 

Sorry for not being very descriptive but it is a 87 NA
