Surface rust so no point modifying 2 ports for the rest to leak.
Also £18 per fitting vs £20 per new pipe
looking round and doing a bit more reading
i think i need 2 of these plus pipe

and probably other bits that o rings etc but unsure cant seem to find a recent thread with pics on or a description of whats needed
seen a guy on you tube replacing a pipe with a copper one with a straight union ,what he did not show was if the 10mm pipe went straight into the ace block
i will keep digging as the copper pipe fix seems to be cheaper option rather than orig pipes ,cheapest for the 2 i got down to £163 plus the other bits
i can cut the pipes under the body a bit back from the block and rejoin if its only a matter of pushing in the 10mm pipe and using orig fittings
edit found a thread that said 3/8 then another saying 10mm, seeing the difference is around 0.4mm should the 10mm still fit
