Nice pics
Need to ask a couple of questions.
Don't you have a charcoal canister hooked up any more ?
Is that hose going from regulator to infront of the throttle flap ?
And are you using the same hose to feed your MAP ? i'ld maybe caution that because there would be fuel in that line. Toyota uses a filter on their Turbo vacuum line to their MAP.
Ild love to know how the MAP does its readings given its not supplied vacuum/pressure as a take off from a manifold.
Lastely your using the Factory location for your oil pressure sender so arent you using the oem unit to show low pressure in your instrument cluster ?
