map sensor block
 

how do i arrange the vacume check valves to stop the map sensor from seeing boost. Because when i use just one it traps the map at 0 psessure and stays there even at idle.

it sounds like you have on backwards, they are one way valves, try to turn it around, you also may need to use more than one

i think i need more than one. im just not sure and was woundering if anyone knew this is just a quick fix till i get a missing link

Re:map sensor block
 

you usually do need more than one, try about 3 of them, but make sure they are facing the righ way.

Re:map sensor block
 

do they need to be facing all the same way is my question. i have the idea of using a y with it comming from the mani to a check to a y with the map on one side and a reversed check on the other

just connect them all in line using a piece of vacuum hose between each one, the last one will go straight into the map sensor
