adrenaline child Posted March 22, 2015 Share Posted March 22, 2015 Hey guys. my 280z project is almost reaching completion. And I want to run direct power from the battery to my fuel pump. With a switch on the interior of the car to turn the pump power on and off. Just wondering if anyone has done this? and are there any issues i may run into in doing that or certain things I should look out for? I hope I am clear in what I'm wanting to do, I try to keep my questions short and sweet. Any help is appreciated. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Tony D Posted March 22, 2015 Share Posted March 22, 2015 Inertia switch in the circuit. Quote Link to comment Share on other sites More sharing options...
adrenaline child Posted March 22, 2015 Author Share Posted March 22, 2015 Is that something I would need? or is it something I would need to look out for or remove? Pardon my ignorance. Quote Link to comment Share on other sites More sharing options...
adrenaline child Posted March 22, 2015 Author Share Posted March 22, 2015 I read up on what that switch does. and I'm assuming I will need one. Anything else I need to do. Will running power direct from the battery cause any problems? Quote Link to comment Share on other sites More sharing options...
Tony D Posted March 22, 2015 Share Posted March 22, 2015 A fuse or circuit breaker at the battery might be advisable. Quote Link to comment Share on other sites More sharing options...
dcoop46 Posted August 22, 2015 Share Posted August 22, 2015 I'm assuming by this time you have found out the fuel pump can't be wired directly to the battery. That would mean the fuel pump would have constant current and be on all the time. You must wire in the ignition circuit. You will need an inertia switch and a 30amp fuse. JEGS sell a fuel pump wiring harness with circuit breaker, fuse, and wiring. You can get an inertia switch on Ebay cheap. Be sure you get the necessary harness with the switch. I am in the process of this endeavor. Hopefully, all will go well. I not as limber or spry as I used to be. Hope yours worked out. Quote Link to comment Share on other sites More sharing options...
jhm Posted August 22, 2015 Share Posted August 22, 2015 Yes, I have an electric auxiliary fuel pump wired as discussed....power from a hot post, fused and inertia switch in line, along with manual switch in cockpit. Only need it when racing; the primary mechanical pump is fine for street use by itself. This seems to be a fairly common setup, so there's really no reason why it won't work for you. What's your intended usage for the vehicle? Quote Link to comment Share on other sites More sharing options...
