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) |

Sean, your faith in Richard at PMO is well placed.
I faxed him about noon Friday and he called at 9:30 this morning. Pretty good service considering I was not a customer and only "inherited" a PMO part. He said they still produce the device and sell it with their carb conversion kits for CIS 911 pumps which are 90 lb. pumps. The high pressure is only created by the restriction created by the FI pressure regulator. He said as long as my return line to the tank has no restrictions (kink/pinch, etc) I can use the clamp to create the restriction in the return line to dial in the correct pressure. The only way the pump would generate 30 lbs. is if some other restriction would plug things up. Think I'll use the system. |
