Thread: Clamps on air intake

Should there be two clamps on my air intake hose ? I have stock hose with the one clamp at airbox with thumbscrew.
The otb end just slips on, should there be another worm clamp ?

Yep. One on each end of the tubing.

That's what I thought, probably my vac leak causing p0171.

Is it 4 inch ?

Thanks

No clamp on the tb side.

I didn't read 97, Nick is correct.

Im always right.

ok, no tb clamp.

Back to changing vac lines, any idea on the size of the small hoses ? are they all mostly one diameter ?

IIRC they are 1/8" inner dia. if you are replacing with aftermarket vac hose it should be fine as along as it they fit on the vac ports. im planning to remove most of the stock plastic vac lines and run either rubber vac line or bend metal line! think it would look cool and last much longer.

I hate the plastic lines, break too easy. Going to replace all with vac hose to try to stop P0171.
I notice everyone talks about the "Tee under the sc snout" ,mine just has an elbow and one line ? Is this normal for a '97 ?
Stupid question I know, but previous owner had other hoses messed up and i am checking everything.

thanks

To answer...yes the '97's are year specific for vac line routing...

I found the vac routing sticker, mine does not show the line to the trans ?

Thanks, that what I thought.
I just need to replace the hose, previous owner had it rigged up badly. Is there a reducer on the tb that takes the size down to match the purge valve ?
I assume that would be the correct way, prev owner has big hose with an adapter connected to the smaller hose.

Maybe take a picture and post it...since you seem to have something we'd actually have to see to correct it?
