A method and apparatus for gaining access to the fluid pressure in which a sharp pointed elongate tube transpierces the resilient wall of tubing of the vacuum system creating an opening through the wall which is in fluid communication with an in-take port of an internal combustion engine. The elongate tube bore providing passage way for fluid pressure transmittal, the elongate tube diameter being small enough to allow elasticity of the resilient wall to close the pierced opening after the elongate tube is withdrawn from the pierced opening. The elongate tube bore passage way providing means to transmit fluid pressure to a pressure responsive device or the like, and also provides means to inject fluid into the fluid that is in communication with the in-take port of an internal combustion engine.

An apparatus for measuring fluid pressure within a resilient tube connected to an internal combustion engine manifold, the apparatus comprising an elongate pressure transmitting tube, an end of said transmitting tube having means to transpierce a wall of the resilient tube, so that the transmitting tube allows pressure communication between the interior of the resilient tube and a means for measuring pressure, and wherein said resilient tube reseals itself when the transmitting tube is removed.
