i know this has been covered but i just need a parts list really as i dont want to order the wrong kit or have issues when installing! i need to install a mechanical water temp and oil pressure guage to my 8v digi, i have chosen 2 racetech ones, both mechanical. the oil pressure goes up to 100psi, with 1/8BSP pressure fitting, is that correct? what else do i need to connect these to the engine?
