Relocating Evap

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

If you guys really want to get anal, the F150 purge noid is designed to mount on the firewall, and the test port is integral.

or you can get the nissan valve thats smaller than the GM or ford valves, and uses a remote test port and rubber lines.

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?

any 'fuel/vapor' rated hose is fine. In CA, id advise you not to smurf with it. Its an emissions system, and is protected the same as cats.

For more info about EVAP, search under my name. I did a whole big thing on it a while back.

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.

Yeah, but those fittings, well lets just say i hate them. way over built for a system that sees no pressure worth discussing.

I deleted my evap completely on my old car.

I moved mine to the back.

It used to be run like this (red is hardline, green is solenoid):



Now its run like this (red is soft fuel line, green is solenoid):



Also took the plug from the back valve cover and plugged the front one with it, and installed a breather on the back one for the pcv:



It cleaned everything up nicely.

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!

I just removed mine and plugged the port on the intake and the line on the firewall. Slowgoat tuned it out for me so I didn't get an SES - Done.

Any negative side effects to removing it completely? I just might do this...

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.
