brake pump

[m-reg]

what fan switches you useing? what temp? I seen on bricks they use saab 9000, splices into top hose , that brake vac pump thing-most diesels seem to use a rotory type so it dont do that clack clack clack thing yeh vw still used it on quite late model vans, once you get the noise in your head you hear em coming a mile off D6s rule. Fan may even save 2 or3 bhp extra for the wheels, they need it lol.
