Anyone do this? Would like to clean up some of the clutter running across the front of the engine. I am talking about the two hoses that run across the front of the engine and has a canister near the passengers side valve cover. I know removing it would cause some issues, but is there a way to cheaply and effectively move it to clean up the engine bay?
Not sure where'd you move it to. I suppose you could 'T' into the brake booster line. Thats the only other 'good' vacuum port on our manifold besides the one up front. Some line and fittings, pull the wires back thru the harness, call it good.
I moved mine to the back of the engine. I bolted it to the rear hoist point. I ran a hose (3/8" I think) from the port on the manifold all the way back and then pulled the wires out of the harness to get them to reach back there... I'll try to dig up a pic
You can see the evap solenoid here, its on the left. Just follow the wiring harness on the passenger side of the fuel rail back towards the firewall... Sorry don't have a better pic
Im thinking about doing the same thing on mine. Are the hoses special for this? I nothiced they have a special clamp on each end and are stiffer than regular hoses. Also what exactly dose it do?
I relocated mine to the firewall near the fuel lines. I did this when I installed a new intake manifold. I don't think I have any pics but I can snap one if somebody wants. I reused the stock lines and fittings which required a good deal of time and effort. Not a good idea if you need to pass emission inspection, but it is very clean looking with only one EVAP line running down the drivers side of the engine and connecting to the front of the intake manifold.
The fittings can be used with reguler hose stock. You can cut the hard plastic line off of the fittings. The hard hose is heat shrunk over the fitting ferrel.
Well got it done last night, just went out and started ripping stuff apart and this is what I ended up with. Maybe some additional cleaning up sometime, but this is what I have for now. Looks a ton better already!
No real problem with a total delete of the evap unless your car has to go through emission inspection and they catch it in the visual inspection. Turn off the light with HP tuners and all is good. Just know that while you drive your killing the Coca Cola bear. LOL...
Do bear in mind when tuning this out that you have over a dozen codes to remove. Not an issue if its you doing it, but it could be a hassle if you have a shop do it and they miss some.
Yeah, ive given up trying to defend emissions systems.
My plan is to modify the system using nissan parts when i do a new tank. Nissan's purge valve is tiny, and the vent control and tank pressure sensor mount to the canister. Smaller, lighter, less plumbing.
Also, being as the GMPP spider manifold doesnt have EVAP provisions per se, i have to make this shit up as i go anyway.
I just walked outside and looked at it. Looks like it should be really easy, anybody know what size caps to cap the ends on the intake and line? Should I just use a rubber vacuum cap? If not what would work better?
Because I personally feel that it is irresponsible to pollute for the hell of it. EVAP costs nothing in terms of power, and is about 7lbs in weight total. Not having it means venting a ton of raw Hydrocarbons into the air. Id rather burn those HC's than waste them.
