This injector hose is in a bad spot and mine was 33 years old.
After taking off bellows and everything else up to throttle body you can actually see the hose with the factory installed clamp that was installed from the bottom of the car.
I used a long flat head screwdriver with a narrow tip and put it in the clamp grooves and tapped the clamp around so I could unscrew it.
On the new hose I split the CSI end in 2 places about 3/8" from the end with a razor blade and put a hose clamp about 1/2 inch back from the cuts.
The split allowed me to center the hose on the plastic nipple.Also the $3.99 11" Harbor Freight pliers with the angled tips helped to center it.
Then I tightened the hose clamp on the split ends.
Then I wedged a large flat head screwdriver on the hose clamp head and levered it toward the nipple till the end of the splits were all the way on the nipple. you may have to tap the clamp around the hose so it levers evenly.
Then I trimmed the split ends of the hose with a razor blade and used a screwdriver to rotate the hose clamp and the hose so I could trim both split ends.
Then it was back to leveraging the hose clamp with the big screwdriver so the now unsplit end of the hose was all the way on the nipple.
Tightened the hose clamp and I was done, no leaks.
That is an SOB of a job on the early Motronic engines, no doubt about it. Thanks for the tip!
Save the manuals!
