Yukond21 Posted March 21, 2015 Share Posted March 21, 2015 I was changing my spark plugs the other day and I found this rubber line coming off of the back of my engine (near the #6 spark plug) that isnt connected to anything. I'm wondering if this is normal? Or should it be connected to something? Maybe a vaccuum line? Many thanks to anyone who can help. Link to comment Share on other sites More sharing options...
Bubbley11 Posted March 22, 2015 Share Posted March 22, 2015 It might be a breather tube also. If you take a photo we might be able to be more helpful Link to comment Share on other sites More sharing options...
Slartibartfast Posted March 22, 2015 Share Posted March 22, 2015 There's a vac line back there that goes from the intake to the fuel pressure regulator. IIRC the drain for the air conditioner's back there too. A picture of what you're looking at would definitely narrow it down! Link to comment Share on other sites More sharing options...
adamzan Posted March 23, 2015 Share Posted March 23, 2015 That sounds like the FPR vacuum line. You should reconnect it if you haven't already. there is a barb fitting for it on the back of the intake. Link to comment Share on other sites More sharing options...
RedPath88 Posted March 25, 2015 Share Posted March 25, 2015 It might be helpful if you can post a picture or several pictures from different angles so we can get a better understanding of what you are seeing Link to comment Share on other sites More sharing options...
ahardb0dy Posted March 26, 2015 Share Posted March 26, 2015 if it's a small diameter line about 1/4" or slightly larger it is for the fuel pressure regulator as was said. Link to comment Share on other sites More sharing options...
Yukond21 Posted March 26, 2015 Author Share Posted March 26, 2015 I can't figure out how to post a picture in a reply here from my phone. What I'll do is take a video of it tonight, post it on YouTube and copy the link here. Thank you all for your help. Link to comment Share on other sites More sharing options...
RedPath88 Posted March 26, 2015 Share Posted March 26, 2015 I just noticed something else too, you have this in the 86.5-89 (TBI) section, but your profile says you have a 93 (MPFI) ? Are we talking about that 93 or another truck in the TBI years, because this does matter when it comes to intake/vacuum related items? If it is the 93, then we can move this to the appropriate section for you. Link to comment Share on other sites More sharing options...
Yukond21 Posted March 26, 2015 Author Share Posted March 26, 2015 Yeah my truck is a 93 with the vg30e mpfi. My mistake. First post lol. Link to comment Share on other sites More sharing options...
RedPath88 Posted March 26, 2015 Share Posted March 26, 2015 All good, thread moved If you ever need it again, feel free to post a request to the Mod Team and we will move it (if appropriate) You can post in the same thread that needs moved, use the "Report" button (probably the quickest option) or shoot one of us a PM.

Yukond21 Posted March 27, 2015 Author Share Posted March 27, 2015 Here's a quick vid I took of it just now. Thanks again everyone. Link to comment Share on other sites More sharing options...
Slartibartfast Posted March 27, 2015 Share Posted March 27, 2015 Yep, looks like the fuel pressure regulator vac line. You'll probably have to feel around until you find the nipple on the regulator. Link to comment Share on other sites More sharing options...
SpecialWarr Posted March 27, 2015 Share Posted March 27, 2015 +1 on that.... taken mine off 4 times in two years. I decided that grease on the nipple was a good thing for all of the vac hoses. Link to comment Share on other sites More sharing options...
Yukond21 Posted March 27, 2015 Author Share Posted March 27, 2015 I finally found the nipple/barb and re connected it. Thanks again for your help everyone! Link to comment Share on other sites More sharing options...
