Greetings,
I read through a ton of threads in the archives in search of an answer to my question....but I'm still unsure! Situation: I'm just about ready to start it up for the first time after rebuilding and installing the 2.0 in my 73 914. The CARBS are Weber 44 IDF's. The fuel pump is a Facet mounted up front under the tank. Fuel filter between tank and pump. Fuel lines are new metal brake lines in the center tunnel, 5/16 rubber hose otherwise. I understand that these carbs need about 3-5 psi. Question: Do I need a fuel pressure regulator? If so - where do I put it? If so - where do I get one?? A lot of threads suggested getting the CB Performance rotary pump setup. I'll keep that in mind but for now I'm using the Facet. Threads also commented that the Facet should be mounted on rubber bushings to reduce noise. I haven't done that...yet. Thanks for your help! I'm only days away from starting her for the FIRST time! Cheers, Nate Pictures are fun, right?! Here's one of the engine and carbs..... Attached image(s) |

Just my 2 cents, but the rotary style fuel pressure regulator that is sold at Bug shops (Bugpack or EMPI bubble pack) and also at Auto Zone (with plastic fittings) is junk. I've had two of them fail in short order. I did replace the plastic fittings with brass units for safety. How do they fail? They don't flow fuel. Their pressure gets lower and lower until no fuel passes. The autopsy revealed no internal damage, but will not allow flow. I have gone to no regulator on my V8 cars and I run two Facets in parallel so I have a backup. The needle and seats can handle the pressure of the Facet.
If your needle and seats cannot handle the Facet pressure and you must run a regulator, I suggest a Holley unit with a good quality gauge mounted away from heat in the engine compartment. My experience with the Holley units has been good on other projects (Lotus 7, Mini GT5 car and Datsun 510)and I have yet to have one fail. Why did I buy the rotary style........I had a cheap streak......It cost me in the long run. David Lee |
