Vacuum line on the back of the air intake

Started installing new vvt solenoids last night in hopes of fixing a shuddering issue. When I removed the air intake cleaner (not sure what it's properly called, but its the big plastic box connected to the air filter housing) the vacuum line on the back snapped off where it connects to the box. The nipple is broken off inside the hose. I assume this will possibly cause some issues with performance so I've ordered a new box, but wondering if anyone else has any experience with this?

 

Fuel pressure regulator, just take it easy until it’s repaired, it only changes pressure 4psi or so if I recall. You’ll be fine to drive it as long as you plug the hole off, put a small screw in the hole

 

Awesome, thanks for the info!

 

I wonder if this is something you could fix with liberal amounts of high-strength epoxy? First to bond the fractured surfaces, then generous extra epoxy around the collar/base to help add some strain-relief around the joint.

 

Depending on what it looks like, he possibly could have drilled it out and tapped the hole with an NPT thread tap and installed an NPT barb with some permatex sealant.

 

They sell bulkhead fitting pipe nipples like this:

$17 GASHER 10PCS Brass Hose Barb Thru-Bulk Bulkhead Fitting 1/4" to 1/4" Barb Hose, Straight Hex Union Fitting with 20PCS Hose Clamp

https://www.amazon.com/GASHER-Thru-Bulk-Bulkhead-Fitting-Straight/dp/B0B6YYVD95 (measure the hose diameter first). Just clean up the hole on the airbox and install this with some RTV sealant.

 

Yes. This is The Way. A much better idea than trying to just epoxy the original plastic nipple back in place.

In an extreme case one could even drill out a round hole to remove a jagged cracked area, then epoxy a new stiff piece of plastic over the clean hole, and tap a hole + put an NPT barb in the added-on plastic. Taking care to be sure there are no plastic shavings or debris left inside the intake housing when done.

 

Id probably go the way of a hose barb bulkhead fitting. Or a rubber grommet of the right ID that would friction fit on the vacuum line well and call it a day.
