Affordable and easy option to replace all the 4wd vacuum conduit for your F-150.
Dorman does a great job making this full vacuum conduit exactly like Ford did. Ford made a terrible design for their 4wd system but now you have a very affordable option to keep it working. Fixed my 4wd not working properly and hopefully will last a while.

Exact fit, exact fix!
I had an issue with my IWEs engaging / disengaging half way and causing a ratcheting sound. I replaced the IWEs and when I did that, noticed water in them and in the hoses. The original hoses were heavily cracked and not supplying a solid vacuum. Since I went through the trouble of replacing the IWEs I figured a new set of hoses couldn't hurt. These lines were identical to the factory (actually had a few more heat shields), fit perfectly and were simple to install. I've had no more issues with noise from the IWEs. In fact, fixing the system has actually saved me money. My fuel mileage has improved in 2WD because the front axel shafts aren't rotating anymore until I engage 4WD (which is almost never). The way Ford designed the system to function. Definitely worth the money.

Good quality
Great price. Arrived quickly. Very good quality. Unfortunately, I have not installed yet due to a heat wave in southern Idaho. I finally installed these vacuum lines in my truck around the end of July 2025. They worked great. They fixed the problem of low vacuum at my IWE's on My 2007 Ford F-150. Now my IWE's do not make the grinding sound. Thank you, Don

Replacement vacuum harness for hub actuators
Why did you pick this product vs others?:I picked this as opposed to OEM for the convince of Amazon. The fit was exact on my 2008 F150 5.4L Every retainer and clamp were perfectly placed for a seamless replacement.

Very reasonably priced.
It worked for my Lincoln Navigator, it does not have tue full lines for the shocks, luckily mine have been deleted and I have regular and not air shocks now. I connected it to both front hubs and back to the engine. Y splitter.

Little short
Needed to extend it like 10-12 inches to follow the oem line, working well so far.
