A couple of these are in stock at the moment if anyone is interested. I try to keep 1 or 2 of them on hand ready for assembly these days.

Charles, are you selling any of these already set up with twin pumps or could you do it at a customer request?

For anything below 600-650whp, it would probably make more sense to swap the internal pump out for a Walbro 450 or Aeromotive 340. This can be done by replacing the jet-pump feature of the proprietary Walbro 255 that the RRP comes with in standard configuration with an external jet pump.

This procedure is not too bad to do, and has been done by a couple customers already. The procedure is to cut the pressure line between the RRP and stock pump housing, and adding a T fitting. Run a hose from this T to the jet pump inlet. The outlet from the jet pump can connect to the unused port on the RRP manifold to send fuel inside there. The suction port on the jet pump needs a short hose laying on the floor of the tank. I can supply the components needed to do this, it can be assembled out of components I already stock.

This would significantly upgrade the output of the RRP without giving up any of its starvation fighting features.

That's above my pay grade. :icon17: Since my car doesn't, or at least hasn't seen track useage I will probably go with your standard twin pump set up with hydramat if I find out that I need to upgrade my fuel system after my tune on Tuesday.
