With the last spruce delivery I got my AN840-4D AN fitting which fits in the transducer block for the manifold air pressure coming from cylinder 3.

The blue hose itself is a VENA TechnoSil heater hose which has 1/4" inner diameter. (spruce part nr 05-00659).

the hose has a temperature range of : -55°C to +180°C (-67°F / +356°F ).
The outer layer is from Silicone VMQ and has a reinforcement with Polyester braiding.
The working pressure at 68°F is 139 psi.

The sillicon hose is attached to the sensor and the AN840-4D using "6504 mini breeze clamps". The are regular hardware clamps that screw on in .250" Thru .625" size.
