puzzledeagle 10 Report post Posted January 31, 2013 Hey guys, I just recently got myself a 69 Mustang with a 302 v8, the wiring was a mess but I finally got that figured out and it now has spark. However the vacuum hoses are a mystery to me as they're all missing, and the service manual I ordered hasn't arrived yet. What goes to where, can anyone point out what to connect here? Thanks in advance. Quote Share this post Link to post Share on other sites

puzzledeagle 10 Report post Posted February 1, 2013 Thanks but none of them seem to match up with my car. The distributor vacuum control valve on mine only has two ports(3,4) Quote Share this post Link to post Share on other sites
Max Power 74 Report post Posted February 1, 2013 Looks like a smog motor in an older chassis? Hell, from the photo it almost looks like a Cleveland. I would get a non-egr intake, a period correct carb, and a distributor for the application and most your vacuum hose problems will go away. The only vacuum hose on a non-air 69 302 with manual brakes should have is a single ported line to a single fitting on the vacuum advance on the dizzy, if I am not mistaken. That and PCV. The 69 manual isn't gonna help you much with a later model mill from the smog era in there. Quote Share this post Link to post Share on other sites

LindenBruce 27 Report post Posted February 2, 2013 Well, if those are the pics of his engine he isn't running a power brake system. So that takes care of one of the lines. I agree with max power. It looks like some transplanted a newer motor into his 69 chassis. Changing out the intake, carb and distributor will go a long way toward fixing a lot of these problems. If you are running an automatic you will need one line from the manifold to the transmission modulator. You will then need to see which of the ports at the carburetor have vacuum only when the throttle is open and run a line from that port to the front port on the distributor. Ignore all the others and plug any that are leaking. Bruce Quote Share this post Link to post Share on other sites
fordguy69 24 Report post Posted February 2, 2013 You've got a late 70's/early 80's smog motor in there. That dual canister vacuum advance is the tell and the vacuum operated EGR. These systems were a nightmare when new. Quote Share this post Link to post Share on other sites
LindenBruce 27 Report post Posted February 2, 2013 Oh boy ain't that da truth. Ever try working on one of Ford's variable venturi carbs? Total nightmare!!! B Quote Share this post Link to post Share on other sites
puzzledeagle 10 Report post Posted February 11, 2013 Thanks guys, I finally got the car running but I still have no clue where most of the vacuum lines go. Not to mention what engine it even is in the first place. Here's more pics of the engine and the markings on it. Google'ing "D4DE-9C485" says that it's the engine for a 1974 Ford Maverick instead. Is this true, could it actually be a Maverick engine? Quote Share this post Link to post Share on other sites
