A "tad" flat? As far as understatements go that's right up there with Monty Python's black knight, "It's only a flesh wound"
It was also hard.
Edit: I have a set of orings on order to carry under the back seat. My concern here is that the old clips break as soon as you touch them. The only original line remaining is from the back of the fuel rail to the HP pump. Perhaps I should just replace it.
What's that one do, anyhow? Is that the pressure control valve return?
