unless it is spec'd for fuel useage too, dnt just use any hydraulic hose, as it is not liner'd suitably

and yeh it is possible to get hydraulic hose that does 20bar+ before going bang, but thats a tad excessive as even if u did manage to bend it round to the fuel filter, it wud tear the filter clean off the inner wing wen it bends itself back

few names of hose supplier chains in the midlands that iv used are IMM, pirtek, james listers. all these will sort u out with something suitable, plus any fittings u might need, and maybe swaging if thats the sort of fitting u go for
