That is the one Jay. I removed all the coolant, intake/ vacumn hoses to have
room to work. I think mine was leaking form the banjo fitting, but it was a
matter of time before the hose failed. That seems like an odd sized hose to
me.On the banjo side I measured .45"/12mm, The hard line end seemed smaller,
the hose on the hard line end was to deteriorated to determine much.
I mocked one up with 1/2' which seemed liked a good fit on the banjo size
but was loose on the hard line side, I clamped it down and it did not leak,
but I am not happy with that solution.
I am going to order the OEM piece, I do not want to go in there again.
BTW I would replace the crush washer and clean up the banjo as well
