The Vanagon fuel pump is designed to run at less than 40 psi. CIS
requires a pump that can deliver at 80 psi, has a check valve, and you
will also need a fuel accumulator. You also need to replace the hoses
with reinforced lines or steel tubes designed for that pressure.

never mind. I went out today, retorqued, drove it, retorqued again.
Seems to
be fine. No leak. Now to figure out my system pressure problem.

If anyone is reading these emails any more, I do have a question for
those
of you who have done this conversion.

What system pressures did you find with a CIS system and a vanagon fuel
pump? Is there residual pressure? Mine drops immediately to zero when I
shut
off the engine. Is there a fuel pump check valve like on the A2's?

Got it into third today - lots of power!
