I know this video is a year old but i appreciate it. Same hose and its dry rotted and spongey. Thanks

[@mjrailey4958]

Well, I had five codes, now down to p0171 p0174. Cleaned mass air flow, throttle body and throttle sensor. Will check for vacuum leaks next. Had very low idle before cleaning everything and would conk out. now has fast idle.thanks for the video! Wish I had my '86 stang. Easy to work on!

I just wanted to say thank you for this video I have a 2002 Ford Explorer and that exact Hope was split in the exact place that you found the split in the hoses that you found oh, it's just amazing how it worked out exactly the same so I just wanted to thank you for this video God bless you in Jesus name and definitely a thumbs-up much appreciated

i have the same problem what’s the size of that vacuum line/tube

[@gloworm106]

Not sure if you found the size, but I just did this hose replacement and bought a Continental 3/8" hose from AutoZone (part 50280). Hopefully this helps anyone else who needs the hose size too.

My scanner gives me P0171, P0172 and P0174 and I'm crazy because I don't know, I've changed valves and nothing.
