PSA: Clamping EVAP hoses under Intake Manifold, the easy way..

[SPCorBUST]

I didn't do any of this.

If you're fine with a strong zip tie, use that instead.

Just make a loop with the zip tie and the line inside of it, leaving an inch of slack. Slide it all the way to the back, and then pull it forward half an inch. Now tighten as you please.

Mine hasn't come off in 3 years, 2 of which were boosted ranging from 9-15 psi. This only takes a minute.

just completely remove it and and call it a day

Just finished doing this to prep for my JRSC coming soon.
I tried it with just unbolting the solenoid from the back of the intake. You can only clamp the hose on the solenoid, but I don't see how you can throw a worm clamp on the hose under the throttle body with everything in the way.

I unbolted the throttle body and A/C compressor and moved them out of the way. It made it so much easier to unmount/mount the solenoid and clamp the hose under the throttle body.

For everyone's reference the torque specs for the throttle body is 71 in-lbs
and the A/C compressor is 26 ft-lbs

Where did you find the info for the throttle body torque specs? Did you happen to mean 17in-lbs instead? I can't find this info anywhere else but it just seemed a little high.

No, 17 in-lbs is way too low.. That's just over 1 ft-lb.
71 in-lbs comes out to 5.9 ft-lbs. And I found it in the service manual.

Sorry never mind I was not paying attention to units. Was thinking everything in ft-lbs. I overtightened mine then to 17 ft-lbs.

edit :

Thanks.

[arren123]

ouch.. Good think the bolts didn't snap.

Yep. I even missed the in-lbs when you pointed it out

Any way we can get the photo in the original post fixed?

For those with a 2017 "red manifold" the hoses and EVAP sensor can be directly seen and accessed between the runners, so no AC removal or sticking hands under intake manifold. The hose behind the throttle body will still require the throttle body to be removed unless you have the hands of a child.

As for the older manifold pic request. I hope This pic helps

here is a manual that describes the process

Thanks for bringing it up. I'll fix it up shortly.

Edit: I don't know why some of the pictures I had backed up in Google including the one on the OP are deleted and can't find any other backup. The picture was basically the EVAP solenoid out, with just the AC compressor out of the way.

I know, old thread. What does the loose end of fuel vapor feed hose number two connect to? One end connects to the purge valve, but what does the other end connect to? Please help, I’ve had my engine out over a year, and am stumped by this one thing. It is marked “fuel vapor feed hose no. 2” in this photo.

I didn't like the idea of having to push the ac up to put it back together under belt tension on my daily driver on a Sunday night at 8pm with no help available and with everything solid to intercooler there was no way I was getting throttle body off with out complete bumper removal to drop intercooler so I attempted the bolt in the back and hoses pulled right off and harness and bam evap is off. Now putting it back together was worth some serious cursing. First off completely forget putting a hose clamp on the line underneath the throttle body. Stainless steel zip tie and some long needle nose is your only chance and mine appears to hold quite well. I beleive my needle nose were 5 inch I'd try for some even skinnier and longer as the a/c gets in the way for when you go to twist/tighten. Other three ends can be hose clamped. Putting buttoned up evap back under with harness attached and lining it up with the hole in the back and then put the nut on? Now that's a real fight, but I did feel a gain in low. To mid range torque with the leaks I always had from day one. Sealed up so Loss of knuckles is worth it.

I'd like to bump this thread as I found a lot of helpful information from it.


Attempted to find my intake leak for my turbo and did not realize these lines needed to be clamped. Total time it took me was an hour, only removing intake pipe and throttle body. For reference, my hand size is a Large in gloves. My knuckles weren't beaten up only my back from leaning over the car. Only real tricky part was putting the EVAP back into the 10mm hole.



1. Disconnect MAF and MAP sensors.
2. Remove intake pipe
3. Remove throttle body (disconnect connector and push it to the side)
4. Disconnect blue connector on back of manifold, you can use this as a reference on where the EVAP is.
5. Remove 10mm nut in the back of the manifold holding in the EVAP (don't drop it)
6. Move the long hose directly under the throttle body out of the way
7. Reach in the back of the manifold and push the EVAP out
8. I managed to use worm clamps on both hoses and the one directly underneath the throttle body (this one was a bit tricky). If using other clamps, it's 9/16 I believe.


Reinstall.
