I am installing a 2.0 engine with Weber 40's fitted. This is my first experience with a carbed engine. It came to me with the fuel block/pressure regulator pictured below. It was marketed or made by PMO. It has a broken fuel barb and I need to repair or replace it.
My question: Is this a good system? It is "1 in/4 out", 2 out to carbs, 1 out to gauge, 1 out to tank. The return to the tank regulates the pressure with a hose clamp that restricts the outflow to the tank. Should I fix or replace this or is there a better system. Haven't checked to see what pump I have yet. It has been moved up front. Haven't talked to PMO yet either. Thanks for any advice. Expect more questions in the next week or two as the install proceeds (wiring? breather hoses?). Stay tuned. Attached image(s) |

Kevin, my thinking exactly.
Brad, how about saying what you were thinking of saying? The PO drove the car (hopped up race engine which blew up) with the PMO set up. I am installing a new engine in the car. I just found the PMO instructions which came with the fuel block/regulator. The device was (is?) intended to be used when converting a FI 911 to carbs. The claim is that you then do not need to change pumps. Same true of the 914 I guess. The directions are very clear, "pressure is controlled by restricting the flow back to the tank" using the "pressure clamp". If I install the rotary from CB, should it be installed in the stock location or up front where the pump is now? I assume I must then plug the return line since it looks like the rotary only has "in" and "out". |
