Part # (OEM or DORMAN?) For dual hose connector that attaches to gas vent canister? (Page 1/1)
Wudman MAY 23, 03:54 PM
Finalized the acquisition of my Dad's 58K mile Indy. It has spent most of the last ten years under a cover or in a garage. Dealing with a few of the usual "bring it back to life" gremlins. The most obvious is a high idle 1,500 rpm-ish. I have pinned down two vacuum leaks. The plug below is a short piece between hard metal lines along the back of the engine compartment that use this connector to plug into the gas vent canister. (At least that is what I think it is.) The other obvious bad line is to the cruise control can. While it appears I can simply use hose that fits, I'd like to try to replace everything as it was when possible.

So any clues to OEM or DORMAN part would be appreciated.

Note that since I am now in California, deleting stuff is not an option. In fact my next road trip is to the SMOG shop which is the final step to complete title change. Any hose that isn't leaking should pass visual, but I prefer "stock" if possible.




Other gremlins appear minor adjustments. I had to move the car about 50 miles from Sutter Creek, CA to the Sacramento area. Ran fine other than the idle. The wife did alert me to the reverse lights flashing on downshifts. I venture this is due to an adjustment my Dad made when attempting to fix the cruise control. He did mention adjusting two switches, one on the brake and another on the clutch.

I figure the big gremlin will be to bring the AC back on line after 20 years of inoperation.

Otherwise it feels cool to be back in a Fiero. (Even the wife was happy for me.)

Usually, the cruise vacuum canister rusts on the bottom side. As a temporary fix, and it's out of sight of inspectors, is to clean the area well, repair it with JB Weld, or Gorilla Tape, and paint over it if you use JB Weld.

Thanks for the info. Zero rust anywhere, just some rotted hoses and cobwebs. Still going through the car for vacuum leaks and other stuff that could fail me at SMOG. This car has been in a "no rust zone" since day one. My Dad was the original owner. (Delivered May 7, 1984). I also have a trailer full of parts and a spare Indy. I will pull the EGR to inspect per the Helms, but will probably order one as well as a new PCV just because.

Again thanks.

Replaced the dual hose fitting with over the counter vacuum hoses. That along with a new cruise control canister hose, has the idle dropping down to about 900-ish after a few minutes. Already ordered a new coolant temp sensor to take a shot at speeding up the idle drop. I think she will pass SMOG with flying colors, but I will check plugs, rotor and cap. Timing or TBI has reportedly never been adjusted.
She sure does idle better because with those vacuum leaks it idled rough.

Even GM did that in later years for the EVAP "can."

Thanks for chiming in Ogre! I hoped that maybe RA may have had optional numbers to cross reference or Dorman may have had an aftermarket piece. Due to the Fiero's unique design, this was likely not going to be the case. Fortunately the same hose that worked for the cruise control was perfect for the larger EVAP can hose. There are so many posts on high idle issues, hopefully this will give those with 2.5L a reminder and solution. The hoses in this 38 year old garage queen literally crumbled when removing. When I cut the hose while at the car part store (to get a cleaner look at the ID, the hoses were shredding fine rubber material on the inside as well. I'd suggest that replacing these hoses ($2.00-$4.00 max), especially the short EVAP can hoses, should be included in any tune up.

Solution part numbers and description
- cruise control to Intake and larger EVAP can hose: total of four feet of - Gates 27043 (inside diameter 5/32 inch)
- smaller EVAP can hose: 1 foot of Gates 27042 (inside diameter 1/4 inch)

A hearty thanks for all you do Ogre. I have been "hovering" for 9 years without a Fiero driver since I sold my last GT prior to moving back to California, so I have not been here much. Good to see some things haven't changed such as your support for the "P" cars we appreciate.
