Would it not be a good idea to put a Dowty seal on the bulkhead connector?  I know they're OK with hydraulic fluid but are they also fuel-proof? 

(I guess my calling them 'Dowty seals' shows my age!!!)

Pete,
You are not alone.....I know them as Dowty too.....
Brass_Machine:
Are we talking about these THINGS

John Rudd:
Looks like it to me.....

And these....
awemawson:
Yes basically an 'O ring' slightly fatter than the thick washer that it is bonded inside, allowing two flat faces to seal as I did in the modified fitting for my JCB 803

So I started to work on this.

This is the piece needed replicating:



Digging through my pile of aluminum, I realized I didn't have a piece that would fit the full circumference of the plate. Not only that, but my small mill could not cut the plate in one go... not enough Y axis. So I used a smaller plate and did the Gcode so I could cut it in two operations. Forgot the camera, so here is the mill cutting the second operation.

On the mill and jigged..



And let the machining begin!



Drilling the mount bolt holes



Finished piece



More to come...
