Whatever you've done, Hedd, I can see the last two pics.

These guys appear to have a selection, Hedd (without having to buy a full kit). You might have to scroll down the page a bit...

Further to all the above and regarding my T type pump, last year unable to find new Tuffnol hex valves I made a couple out of thin flat brass sheet. They worked great and at the time I wondered why they'd not originally been made of that material. After around 3 months of not being exercised, the pump failed to deliver; stripping it down I found both valves stuck to their seatings, could only have been the stale petrol wots done it I suppose. Does this happen to the Tuffnol ones does anybody know?
ps. does anyone know offhand what size of Tuffnol hex to order from Flexolite for a T pump?

[John Gould]

Oops, ignore the ps. I now see it's the 15/32" ones!

I wish I had a spare main body section, I think the thread holding the top on is on its last legs, but otherwise it’s working well and seeing all those Flexolite spares has inspired me to put a spares pack together.

The thread holding the steel cap on the top of the pump is 1/4 BSF. I noticed that the threaded hole on a pump I was overhauling was somewhat deeper than the length of bolt holding the cap on, so I measured the depth of threaded hole and found a longer bolt which engaged with more of the thread.

Ah, thanks David, I’ll give that a try, I’m using the original at the moment.
