Cold Start Vacuum

Anyone know anything about this part? It broke when pulling the motor and need to get another one. It appears to be vacuum lines for the fuel system.

Anyone know what Toyota calls it or have a part number? edit: for 92 Pickup 3.0 5spd 4wd

Thanks

Here is a pic of the location:

Can't remember if it went to the charcoal canister. It sits at the back of the motor though. I posted a pic of the general location.

how about getting the FSM for your truck it's free and check out the vacuum diagrams for it in it. If they aren't in there then Autozone has good vacuum diagrams as well. If not those places then you can find your part number and diagrams over on toyotapartszone with an approx cost.

TVV stands for "Thermal Vacuum Valve" in the FSM

In the parts book:
VALVE, BIMETAL VACUUM SWITCHING, NO.1
**925-05047

http://www.toyotapartszone.com/oem/t...925-05047.html

Search on this forum for TVV; many have reported successfully repairing one. I found that the plastic head was too degraded to successfully repair.
