Question about cone install

[Humango]

I'm doing the cone filter upgrade and just wanted to know what to do with the purge canister hose connection and any other tips, thanks.43184319

[MikeFleming]

his is one of hte issues with installing cone filters - there is no provision for the evap hose. Most folks remove the charcoal canister and associated hoses. Which is illegal, btw.

[Humango]

Thanks again Mike for your help, but is their any negative effect to removing the canister?

[MikeFleming]

Besides the increase in evaporative emissions and the fire hazard of dumping raw fuel fumes near a hot exhaust system?

Probably not.

negatives: empty bolt holes on the fender :(
Positives: more roomy :)

You can get a later type (87 on) canister off a 4 cyl or V8 car in any salvage yard which uses small vac hose which connects to to any source of eng intake manifold vac.

If I fab a collar w/t-fitting for purge pipe to put between the cone filter and vam, would that harm the vam?

All that comes out of the hose is vapors from your gas tank. Shouldn't cause any problems as that is where the original connection was from a systems standpoint. I've also seen installations where a fitting was added to the cone filter itself and the connection was made there. HTH

... small vac hose which connects to to any source of eng intake manifold vac. Not a good idea. Manifold vacuum is too strong. we want an inches of water depression to carry the fuel vapors away, not an inches of mercury (100 times too strong). That much suction (i.e., manifold vac) has been known to pull the charcoal pieces out of the canister. Besides in turbocharged engines all "vacuum" sources are also pressure sources.

Vent it to the clean side of the air filter area.

Forced4 used to have a description of how they recommend you solve the issue. Basically you cut a small hole in the rubber end of the filter and attach a PVC fitting. You can then connect the canister to the fitting with a piece of heater hose. The fitting I used is an elbow barbed on one side of the fitting for the hose and has a male threaded end on the other side. Stick the male screwed side through the rubber on the filter and then attach a female threaded fitting onto the inside to hold it in place. Works great. Let me see if I can find a close up of my setup.

[Humango]

Well after a little fabrication this is what I came up with.....
















so what do you think?

[Humango]

This is the unit installed.

[BrianM]

That looks great. My setup is very similar but fitting is mounted on the end. Same difference though.

[MikeFleming]

Is that dark turquoise?

[Humango]

@Brian, thanks, cost me less than $10 for the adapter which still allows me to return to stock if needed.
@ Mike, hey Mike, that's dark blue, and please don't ban me, but an eBay filter, funds tight.

[MikeFleming]

I was referring to the nail polish color. That could be a dark blue also.

Not to worry - Mitch has the ban hammer this week.
