Hi,
I just bought a used decel valve sight unseen and it is different to the one on my 77 Carrera 3.0.
The one on my car has a small port on the top and a single large port on the bottom. I do not know the part number. Sorry about the poor picture but its hard to get my iPad in there!
The one I bought is a Bosch 0280160324 it has a small port on the top and two large ports on the bottom that are different sizes. The bottom middle port is about half the diameter of the one that is offset to the side.
Can I use this valve by plugging up one of the ports?
If so which one do I plug?
Final question how do I test this? I've read here that you can test a single port valve by sealing the top port with your finger and sucking on the bottom port but what do you do to test with two ports?.
Cheers
Bill
