Has anyone had any experience of fitting an SPA boost and oil temp gauge. considering tapping sump plug for the oil temp switch, but the boost requires either a tap into the inlet manifold or putting a piece of aluminium pipe in the inlet or in the hose to the inlet manifold with a 1/8 bsp thread to accept their pressure sensor. any ideas please as the sensor is quite large (about 2.5 inches)any help would be appreciated
Thanks Sandman.
