Vacum hose question need help please

I have a 97 f150 xlt 4x4 and I've noticed a hose coming out the intake running into a fitting on the firewall driver side the line is a dealer part according to autozone ! The hose is really dry rotted could this hose cause my truck to have any hesitation at all and make my check engine light stay on ? Any advice is greatly appreciated

 

you talking about the hose thats going into the brake booster?

 

Yes

 

The hose looks like foam and is brittle

 

if its the brake booster hose you should definitely get that replaced. it could case you to have some brake problems if its breaks since it wouldnt be keeping a vaccum condition in the booster. im not sure if that would turn your CEL on or cause the truck to run ****ty. im sure someone will chime in with more info.

 

Ok thanks will do

 

Yes itll make the truck run terrible! Replace it right away

 

You can use regular vaccum hose for that line, the idiots at vatozone have no idea what they are talking about.

 

x2 I think its 3/8
