I am currently running on my 99 uk turbo, fmic, induction kit, fuel pump/reg and samco hose running from manifold to boost connection on dump valve.

Dump valve is a turbo xs RFL.

Its the vacume hose into dump valve that keeps splitting. Ive rubbed the brass inlet on the dump valve down incase of sharp edges but hose has split 4 or 5 times now.

Any suggestions on cause of this or how to remedy it?

Cheers
