Man thanks for showing where the hose goes to the carburetor
👍 Screwdriver, drawer, looks like mine
Great video, gotta replace the same thing on my Pontiac Catalina. I also enjoy your humor, subscribing!
Awesome! Thank you!
THANK YOU- the little rubber hose on the manifold end of the vacuum line was the issue for me!
I’m happy it helped!!
great easy vid !
Lol, I haven't heard "grody" for AWHILE!
Really fun video brother. I got a '79 Silverado . I love my truck.
Hey brotha what's your wheel and tire set up got the same rig and love your setup thanks much god bless
thanks for the help
I had the same leak on my c3 corvette and replaced to o ring, but it still leaked a little. So, I slipped another o ring on it just above the first o ring and slid it up to the ridge that the bracket holds in. Problem solved. If yours is still leaking you might want to try that. 🖖🏻
Mine was leaking internally. It has several thousand miles on it without issue at this point.
hey, appreciate your video... I have a 84 cucv m1009 and it pretty much shifts too late from 1st to 2nd... what would you recommend to get it fixed? should I either replace the valve @ the injectionpump upwards or "decrease the screw" at the modulator? ... thanks in advance for your advice ;-) best regards from germany
I've been battling this same thing in mine. it just shifts too hard and late. I am looking through vacuum leaks and adjusting the valve to get it right. Make sure you dont have any vacuum leaks because that will make the modulator ineffective and you'll have a hard 1-2 shift at high RPM.
how come no fluid came out? did you drain ? mine is leaking but alot of fluid comes out when i remove the modulater
My fluid was about 2 quarts low.
I have a question I have a 1978 C10 half ton I can run through all the gears after shifter it's an automatic I can see it switching the gears on the transmission but the truck won't move is this something with the transmission or something to do with shifting in the column can you help me out please
If you can see the arm and hear the clicks of the cam in the transmission underneath, it's likely a transmission problem.
@@BurnoutsAndRotorblades it was actually the linkage it wasn't in the frame the piece it has the spring 🤦♂️
