Need a vacuum hose diagram ford 460 engine in 1989 motorhome

Just go to an auto parts store/distributor and tell them you want a fan/alternator belt for a 1989 Econoline with a 460 engine. That's all you have to say. Speak nothing of Motorhome, it really screws them up when you say that. All the have to know is that it's an Econoline 350 with the 460 engine. I have 2, an 87 and 88 Tioga with 460 engines and I never mention the word motorhome. I'm scrapping the 87 and have all kinds of stuff to sell from it. A complete front end with fenders, hood, doors windshield and bumper in good shape. I'm putting the seats and refrigerator in my 1975 18 foot Midas on a Dodge chassis, now with a small block Chevy 383 and 700R4 trans in it. Already put all the cabinets and booth from the 87 30 foot Tioga into this little 18 footer. Oh, the front end fits from 83 to 91.

here are two basic vacuum diagrams from a 390 engine, one or the other should work for you depending on your distributor vacuum advance setup. good luck

Is it a vacuum hose? Find the open hole in the plenum (you should hear a pronounced hissing sound with the engine running). THAT is where the hose goes.

You should be able to hear a sucking sound from where the line is supposed to go. Probably on the base of the carby. You can spray a little aero start around where you think the leak might be ie: carby. the aero start will be sucked into the open vacume port & the revs of the motor will change. Sorry I don't know exactly where it goes.

I do not have any diagrams but HERE are a good set of written instructions, this is an easy engine to work on.

Hope this help.

Hydraboost works off of your power steering pump, you will have hoses between them, if it is conventional vacuum then it will have a large round vacuum chamber behind the master cylinder, with one hose running to the engine.
