z ya Posted October 8, 2011 Share Posted October 8, 2011 I know you cant run the the mech fuel pump with the JTR mounts but has anyone fabbed any mounts with the V8 that will allow it?? This is with still keeping the motor set back like the JTR not Hooker mounts. I really cant stand the sound of the damn electrics and have a a nice Carter 172 pump at home.

Pyro Posted October 8, 2011 Share Posted October 8, 2011 Just use the stock efi pump with a return style fuel pressure regulator. A quiet and durable setup. Aeromotive makes a nice return style fpr that goes down to 5 psi. Quote Link to comment Share on other sites More sharing options...

Thing is I already have a nice Carter 172 mech pump with the nice filter and proper length pump to carb -8 line. Sure would be nice to have no noise and the reliability of a mech pump.

emeraldlion Posted October 9, 2011 Share Posted October 9, 2011 He is talking about the stock datsun electric fuel pump. I have been over this with them in several posts. The stock datsun efi fuel pump will flow quite a bit of fuel at lower psi. You just have to make sure you have a quality fpr that will regulate the 35psi down to 4.5-5.5 or whatever your carb likes.

Oh ok...so use a 280z fuel pump?? Im guessing the tank as well. The aeromotive fpr looks like it wont work. The low pressure spring is for 3-25 and high pressure from 25-65 or something.

Tony D Posted October 10, 2011 Share Posted October 10, 2011 I made 350+ RWHP on the stock EFI pump running no more than 23psi. They are extremely quiet when at idle and only pumping 3.5psi through a return-style regulator. At 23-25psi (21-22psi of boost) nobody really was interested in what noise the fuel pump was making! Why reinvent the wheel? If it fits in the chassis, use it. I've used on on the carbed blow-through setup for years. Fuel Flow for 350HP is fuel flow for 350HP. Showed no signs of being undersized in that application whatsoever. Quote Link to comment Share on other sites More sharing options...
z ya Posted October 10, 2011 Author Share Posted October 10, 2011 Thanks Tony! Is the 280z gas tank/fuel pump a direct swap in the 240? Quote Link to comment Share on other sites More sharing options...
tbellis Posted October 12, 2011 Share Posted October 12, 2011 I run the pressure switch to power a relay that will only start the pump when oil pressure is reached. This keeps things quite until the engine starts, the engine exhaust make it difficult to hear the pump. You do have to prime the fuel system if you change a carb or something.

z ya Posted October 14, 2011 Author Share Posted October 14, 2011 Thanks guys for the info. Well I think for pure ease and budget Im going to keep what I have for now. Its a Summit 140GPH electric pump. Its a bit loud but Im sure if I run it with a return it will be quieter than the deadhead set up my dad was using. Most liely with a have the stock 240 tank sumped as well. Quote Link to comment Share on other sites More sharing options...
sweetride2go Posted October 19, 2011 Share Posted October 19, 2011 Find a pump using gearator guts instead of the standard rotary vane style like the carter. However, they cost more. Cheers Ryan~ Quote Link to comment Share on other sites More sharing options...
