Thanks for the info. I've got the same setup going in my project too. Paul @ Hydratech told me it's not compatible with the small reservoir of the March p/s box. Now I know what I've got to get to make it work.
Glad to help. I am going to machine a new cap for my reservoir and do away with the fill neck entirely. I'll post pics when it's done if you are interested.
that kinda sucks what about other companys serpentine belt conversion. i rather run a abspowerbrake electric power brake system. basicly has a small air pump that has more psi then anything else also keeps enough in the system for 114 stomps with the car turned off.
The serpentine system has nothing to do with the problem built into the March pump.
I chose the march pump because it compliments the rest of the accessories on the engine and looks nicer then the standard pump. The fix I mention was relatively inexpensive and does not look too bad either.
