need a good oem knock sensor 1988 mitsubishi starion

Not my week. I'm dealing with the loss of our family dog and on the same day I damaged the bumper on a Aston Martin. I was on the phone with my wife as she's relaying the bad news from the vet about our beloved Cocker Spaniel, at the same time I was unloading a Aston Martin in front of customers house.   I'm alwalys super careful with these cars cuz they expensive as hell. One of the wooden ramps I used to make sure low clearance cars don't bottom out on the bed of the truck jumped up naili

wasnt even my race, i just went to watch.. lol.. they took off and i nearly killed my car and while catching up i figured id just run down the lead car while i was at it, they only had about a bus lengths head start..... ruined the poor kids night.... the dude in the honda said, i thought you said your car was slow, my response was.. well you said yours was fast so i guess we both lied.. haha     video from the honda..  

This winter I'm planning on the inevitable tbi rebuild. Was wondering if the fuel pressure needs to be let out or de-pressurized before tear down?
