Just made purchase of a 1984 300 dt ,runs well with around 230k.The vacuum pump is out ,the car wont turn off with out opening the hood ,thats nice. Ran a couple of 6 ft vacuum hoses from the vacuum turn off at the alda to inside the car,the hose runs nicely along the drip rail to the back window slightly opened,the hood ,at its corner ,allows hose travel out the engine area.The trick is a mighty vac hand pump sitting on the passenger seat,very backyard mechanic ,but it works.My main question is the vac pump on the front of the engine not working ,will this harm anything with it out?
