mga friends tanong ko lang po sa inyo kung puwede po ang vacuum gauge sa diesel engine gusto ko po kasi kabitan kotse namin by the way makina po pala namin in 4d55 mitsubishi san po ba ikakabit yung vacuum hose
while engine is running, unplug and check small hoses and check if it's vacuum...
then you can hook it there with a "T" or better trace it up to the source (vacuum pump) and hook it there... the "T" comes free when you buy the guage...
make sure you buy a vacuum/boost gauge. so dual purpose...
dun sa idle up switch pede ikabit yun vacuum gauge. basically it tells you the amount of air that is being suck by the engine. the more air, the more fuel is injected to the engine. it also serves as a consumption gauge sa mga euro cars like bmw and mb.
sir afrasay san po ba yung sinasabi niyo po na idle pump ba yun kasi po nung chineck ko yung injection pump na may hose sa air wala po siyang hangin dapat po kasi daw kapag naka start makina at binunot yung hose tataas yung minor and magiging palyado and wala din pong nangyari help naman po
