So, I just ordered a P4070 Carter electric fuel pump, a regulator, and a fuel pressure gauge. I was wondering if, since my regulator has two outlets, I can get rid of some of the plumbing associated with the stock setup. I'm planning to replace the mechanical fuel pump and build my own block-off plate and gasket for the hole out of aluminum and was hoping I could get rid of the stock fuel rail and other stuff. Anyone have an opinion on this? Any pictures? It's purely aesthetic reasons for doing this, so anything I can do to simplify the engine compartment would be a plus.

I'm using the following webpage as a reference:

What car do you have? FI or carbed?

What ever floats your boat. If you just install a RX-7 pump you don't need a regulator. They will supply all the fuel you ever need for your carbs. Since you said that you were going to cover the hole in the head you must talking of a 240z. I have been running a RX-7 pump for 8 years. We even tried one on a set of triple Webbers on a vary built 280 engine and it supplied them just fine. $15.00 at the U-pull- it. Just use one from a carbed RX NOT a injected one. The fuel rail functions to supply cool fuel to the carbs by recirculating the excess fuel back to the gas tank , thus cooling the rail. You might think of a method of stopping the gas flow in the event of a accident and you cannot turn off the key! An a inertia switch to cut the power if you are in a wreck is one option. I installed a simple pressure switch that will cut power if my oil pressure drops below 7 PSI.

I have just completed the conversion from EFI to Carbs on a 280z, I was not sure if the fuel pump would supply 3.5 psi for the carbs, so I installed a regulator. I would like to know more about the pressure switch that you installed beandip to place on my car,

Thanks

What year RX7 should the fuel pump come from?

Sorry for the lack of details, it's a '72 240Z. The previous owner had installed a fuel pump that I believe he got from a FI car that he parted and hooked it up to a switch just to prime the fuel system prior to turning it over - he'd shut it down once the car was running. That thing was loud, though, and was not working right by the time I got the car, so I pulled it out and just ran the mechanical pump without issue (I think). However, I've had some random occasional loss of power that MAY be related to fuel pressure, so I wanted the gauge/regulator/electric pump to balance it all out and let me know that I really have pressure - I kind of worry that my tank may be rusty, although my inline fuel filters never get dirty. I think I'm gonna install this today after I adjust my valves and cam timing. We'll see if I get there...
