i believe the vsv bleed's pressure into the fuel tank ,help's the pump(s)from cavitating.the 2jz actually has a little pressure tank under the manifold with the vsv mounted to it.becauseican;1320162 said:So does the 1jz use a VSV in the Charcol circut?, by the looks of the pic it just goes through thte steel pipe then to the TB.

aphxero;1391405 said:Nope it's one specific vacuum port. Goes straight ot the side just in front of the throttle place. Points towards the tps side.
becauseican;1418712 said:I have a standalone EMS with a custom made engine harness, and removed the VSV's etc., so I have nothing to control the VSV. I just have the JZA70 charcol can hooked up to the port on the TB with the inline check valve, no VSV. I have been running it this way all summer with no problems. Just wondering if being "open" full time wil cause any problems?
