Early LA eng by pass hose

They do sell both dia. stainless fittings for the intake. 69 on back with the lower hose on the left take the smaller dia. hose. 70 and up with the aluminum pump and the lower hose on the right take the larger dia. Some one switched something on your car . but if your car has a cast steel pump it should take the smaller hose. I have used the rubber bushing in the past with no problem a NAPA part. Today I would get the right hose , Only because if your going to do it right use what it came with. But thats just me.
