Do you have a pic of the part you need? Do the 550 taps have diaphragms?

It's not this bit is it?:-

Meh....just looked up a pic..........never realised vacuum taps were used that early :oops: I have a few spare taps, if you can post a pic, I may be able to find a decent diaphragm.

If it's the hexagonal one, this is the cheapest new one I can find:-

Not great with the current transfer rate :(

hi Its like the one you sent in link. But at the pointed end [top] it has a flap type hole. Think gt750 tap is the same as 74L model
does have same part number.
Will try to post photo later
Thanks Ray
