Primary Fuel Filter connections Question

[seumask]

I am trying to replace the fuel lines from the tank to engine fuel pump on my 2001 Jeanneau Sun Odyssey 37 and I mistakenly damaged one of the copper pipes going into the Primary fuel filter and would like to replace it. Can anyone advise on what pipe fittings these are likely to be and if there is a replacement that is not such a soft copper pipe, possibly with barbs on it to push the new pipe on to. I neglected to measure while i was on the boat but I'm pretty sure its a common size! the likely pipe size to the filter pictured below.

8mm hose tails are what you want, but you will have to measure your threads as could be m14 or 1/2" unf. Jubilee clips are not the best for small pipework like that as they distort at small diameters Mikalor type are far better.

Without measuring it's a bit of a guessing game, but the small ones are maybe 1/4" BSP.

Surely not BSP on a CAV filter head?

As you say, it needs identifying, not guessing.
