Note to self.......replace vacuum lines. If a vacuum line gets old,hard, and unflexible, lets just replace it. I know it's frustrating sometimes to stop what your doing and make a seperate trip to the vacuum line store but, it is so much easier working with new lines than old ones. This lesson was refreshed for me last night as I struggled for 40 minutes in the cold trying to make old hard hoses fit. a quick trip and 5 dollars later, parts slid on like warm butter.

Hmm....

 

You raise a good point. I just ordered stuff for a tuneup and didn't even think about vacuum line which is, as far as I know original equipment. Any chance you recall what size line you got and how much of it? (carbed '89 ea81 hatch)

 

thanks

I was not doing a complete overhaul on ALL the vacuum hoses I just bought about 4 feet of 5/32" size hoses. More than enough for the egr solenoid I was tampering with. A good Idea is to keep some spare feet of it of variously used sizes just for "in-case". I paid about 5 dollars for 4 feet. something like that

I did the same thing last year. Went the extra step of putting hose clamps on the pcv hoses as well in a vacuum leak ending crusade. Just another piece of the puzzle in getting a perfectly smooth running old motor!

+ 1 for new vac lines

 

Just be sure to fish out the "orifice" plugs from the old line. not all the hoses have them, but I think there are at least 3 or 4 on all the older hitachi carbed stuff

Can we get the PCV & crankcase vent hoses somewhere other than a dealer for an 85 EA82 carbed? What are people substituting for the preformed ones? I'm just about finished replacing my engine and need to do something for those hoses.

Carquest sells EVAP rated hose in large diameters. 5/8ths IIRC for the PCV hoses.

 

The ones to that go to the ASV boxes will need an adapter cause they flare out to like 3/4 where they meet the box. Although I would ditch that stuff, and just plug the holes in the exhasut ports, and get rid of the boxes and asociated hoses.
