Fuel Pressure Gauge Question
I got a fuel pressure gauge to fill my gauge pod.
I am not sure where to install the pressure sensor. Does anyone know a good location to install it so I can finish the gauge install?

Which fuel pressure do you wish to monitor ....... the pressure created from the pump in the fuel tank or the pressure from the HPFP ..... ??

Do you know where I should track fuel to monitor for proper fuel pressure? Or would you recommend a better item to track besides fuel pressure to fill the gauge slot?

What pressure do you want to monitor? Port injectors or Direct Injectors? It honestly sounds like you should NOT be turboing your car. Or paying someone to do everything for you. |

Or, if there someone out there kind enough to help a guy out on what fuel pressure to monitor for turbo purposes, I would appreciate your input. Also, this gauge, tbh, is just a slot filler. Of my choices, it seemed the most useful. None of the choices seemed that great aside from what I already have.
I am not looking for your advice on how I should mod my car or anything else. I am asking where I should place a fuel pressure sensor for a gauge. If you don't know (just like me) then I suppose you don't need to answer unless it is constructive. Read my signature. If I am just too fkn stupid for you, just move on. Thanks!

Or, or, or! Would an EGT gauge be more beneficial than fuel pressure? I just didn't have any more options.
EGT, Fuel pressure, or ethanol content/fuel temp were the only options I had. I am wondering now if EGT might have been better...

If you just want to monitor something in reference to fuel pressure, I reckon it would make sense to monitor the pressure of the port injectors ...... maybe tap into the fuel rail ...... What you may wish to do is let us know what all you are planning on measuring ....... then the FI folks in the know, could recommend what else to monitor ..... humfrz |

Innovate scg-1 boost controller Innovative mtx-d oil temp/pressure Innovative mtx-d fuel pressure If someone wants to suggest a better item to monitor, I am all ears and I'll get that gauge instead, otherwise I'll have an empty hole in the gauge pod (I know, air bag and yummy gauges in case of wreck). Going to see if I can disable that one airbag. I am a newbie, yes. I don't deny it. That's not going to stop me from boosting and learning all about it. I am trying to learn to tune myself too (the first tune will be from Shiv). Any helpful posts/comments are greatly appreciated. Sent from my SM-G950U using Tapatalk

I'd rather be harsh with the truth than have someone jump in over their head and destroy their engine.
Not saying OP doesn't, but I err on the side of caution. If you can only have 3 gauges... Boost/AFR Like you have. Oil temp/Press EGT On top of that I'd personally have water temp. One with actual numbers, but there are other options like an OBD2 reader. Fuel Press is nice but imo unneeded. Maybe if you track it and are seeing enough side G to cause fuel starvation. Gauges to help tune. Boost AFR Fuel Press EGT Gauges to make sure the car is running ok while driving. Boost AFR EGT Oil Temp/Press Water Temp. Can also throw flex fuel gauge (ethanol content) in there as well if going that route. Edit: If tuned properly with that boost/AFR gauge the ecu should pull boost and possibly even be able to put the car into limp mode if the car starts going lean from fuel starvation. |

Here's a DIY I posted a while back on my fuel pressure gauge install: http://www.ft86club.com/forums/showthread.php?t=121645
There stock ECU already has a fuel pressure sensor for the direct injection rail. This sensor reads the low-pressure supplied by the in-tank pump. -Matt |
