Just cut a 500ml bottle in half and use that to catch any fuel that leaks when you take the old one off. The stock fuel system in the 370z has proven to flow more than adequately for any amount of power you are safe to generate on a stock engine. Does it matter which fuel rail its on? The tanks are similar overall shapes, but the dimensions are rather different. It worked great and the car performs great. As for the 90° hardline, yea, you can remove it. Right after the fuel filter is the easiest. These fuel lines are available for aftermarket induction setups as well so that you can easily plumb your custom induction with high-quality fuel hose.
So unless you have come up with a specific reason that you need to change the fuel pressure, you arent really ever going to need to. But their diagram would suggest that it regulates the output to 52psi Anyone clear this up for me and tell me what to put where since I've pickled my head? Tuning E85 with the 1000cc is more like tuning gasline with 700cc or so. The correct and specific language of this trouble code is Fuel System Lean, Bank 1. Q: Will installing an aftermarket fuel pressure regulator add horsepower to my vehicle? Glad someone knows what they doing So from my understanding of what Tricky Ricky said I've got it set up correct. The G37s with a 350z fuel pump assembly must either have a modified version of it that is taller, or the G37s with the 370z fuel pump assembly must have a modified version of it that is shorter? This means at idle vacuum, the fuel pressure is lower.
A 2:1, or 3:1 would be a rising rate. Most fuel injected vehicles come straight from the factory with a fuel pressure regulator. Notice the 600whp graph starts to taper up at the end due to maxing out the injectors. Andy's Auto Sport is the ultimate shopping destination for your Nissan 350z fuel pressure regulator needs! With a high performance motor, an adjustable fuel pressure regulator is needed to increase the amount of fuel given to the engine since larger injectors and fuel pump will be utilized. So instead of messing with complicated computers and injection duty cycles, these systems just increase fuel pressure to add fuel.
Perhaps today I will go into this page and update it to explain a lot more and with what findings we have had since actually using these fuel pumps after modifications. Additional Components: High performance fuel pumps put a greater load on the wiring, and the small factory wires can not only get very hot to the touch, but they can prevent your new pumps from performing at their best. Thought i had this sussed then after i had a quick check to see how others had it set up I've totally confused myself This is how i have it mocked just now is this correct? Many of us have been running them like this for years with out a problem. The pressure in the manifold pushes back on the fuel trying to come out of the injectors. Any insight on that, Sam? An external regulator is required. Great, thanks mate However, I struggle to see how that would work efficiently. A: The fuel pressure regulator regulates the fuel pressure that goes into the engine.
Here at Andy's we have a fantastic selection of Nissan 350z fuel pressure regulators. These regulators increase fuel pressure at a multiplication factor of boost. If your fuel lines are old, cracked, or torn it can potentially cause a fuel leak that will destroy your car and put your life in jeopardy. I tried to adjust it back down but it won't go below 40-42 psi and I am a bit worried about this. I then tried to find something on the web to clear it up for me but the best i could get was this from fuel lab. I agree that upping base pressure isnt recommended however its a very common route albeit less common nowadays, I've never needed to fit an adjustable reg on any of my modified turbo cars Okay, that makes a bit more sense now.
Using an external regulator allows you to control exactly what your fuel pressure is. So I decided I would make my life easier, preserve my engine, and learn on a more typical configuration. Anyone have any idea regarding this? It also helps prevent failure of the injector coil. Q: How do you install a fuel pressure regulator? So what happens in that system if you don't have a regulator? The 350z unit has all its passage ways and plumbing molded into the housing, so you cannot clearly see how it is plumbed. If this is not the case, time for a new pressure regulator. Also, as the car idles injectors are absorbing some of the fuel pressure by releasing. I was having a lot of trouble getting the car to run well in all conditions.
I can also add details into specifics with the rest of the 370z fuel system so people know exactly what they are doing and why to do it. I elected to switch to E85 to, in essense, water down my injector size. I am not sure at this point which G37s use the 350z assembly. It ignites easily and therefore is a major safety hazard for any vehicle. A: Not directly, but when adding an aftermarket fuel pressure regulator and high flow fuel pump to your modified engine, it can help deliver the additional fuel needed for optimum performance. Also best to remove the battery and wait over night for the pressure to go down in the fuel system.
I assume the regulator isn't put before the injectors simply so you don't end up in a situation where you get a massive need for fuel and the regulator can't open quickly enough to supply it. At Andy's Auto Sport, we have a huge variety of Nissan 350z fuel pressure regulators to ensure that you have every fuel pressure regulator option available to you. Massive help guys thanks, helping me push on with this build. They go inline down from the factory regulators and only start to add pressure under boost. So you will see a low fuel det map engine is happy and ignition advance multiplexor at it's peak , and you will see a high det fuel map richer map that will have more fuel for knock detection condition. I will post a link either tonight or tomorrow to this document. Enjoy your properly fueled car! I'm sure there will be more questions over the next few days regarding building to boost.
