Silicone Vacuum Hose / Line Sizes? (1 Viewer)

[Red Merle]

Update: Almost a month later and everything seems to be working well. Only issues I've had lately are a pressurized gas tank and a P0420 code which I firmly believe are completely unrelated to the vacuum hoses.

The pressurized gas tank is probably the charcoal canister clog that everyone seems to have.

You can replace it with a GM one. VC120, I believe. AutoZone has them for like $60.

These are the part numbers you need. These part numbers replace every single vacuum and EVAP line under the hood. Beyond the 3.5mm ID hose, everything else will be location and duty specific.

The second number after the 10-digit Toyota part number will be the quantity you need. This will only be applicable to 8/1992-1/1998 FZJ80 trucks for the US market:

90999-92003: 8 (cut to fit)
25695-66010: 1 (formed, EGR)
95337-06020: 1 (cut to fit)
95333-06010: 1 (cut to fit)
90910-05212: 1 (formed)
90910-05217: 1 (formed)
95334-06010: 1 (cut to fit: FPR)
77795-60020: 1 (formed, EVAP)
77754-60180: 1 (formed, EVAP)
23273-66031: 1 (formed, EVAP)
77279-60020: 1 (formed, EVAP)
12261-66021: 1 (formed, PCV)
12262-66021: 1 (formed, VC ventilation)

I generally recommend replacing the check valves as well since they are stupid cheap: 90917-10049: Two for the 1993-1994 trucks; One for the 1995-1997 trucks.

Any dealership bumpkin punching numbers can get you these part numbers.

What's a ball park price for all of the above? Rough ball park is fine?

Yes, eventually I'll go this route however for now I've just bypassed it. Seemed to do the trick!

Careful with that. People have reported engine fires that they suspect were caused by the bypass method. I would install the canister, just to be safe.

Did u ever figure the size of the smallest vacuum lines?
Are they 3.5mm 0r 3mm?

I don't remember if I ever figured it out, but I ended up using the 3.5mm hose and it worked fine. No problems here.

“The small hose is 3.5mm ID.

It is serviced in 2/3 of a meter and 1 meter lengths

2/3 meter is 90999-92003

1 meter is 90999-92004”
