Rotate the TU HPFP Connector **NO MORE MODDING THE WIRING HARNESS**

Made a video on how to rotate the TU HPFP connector. This way, there's no need to mod the wiring harness or add an extension, just plug it in the same as stock. Hope this helps.

Thanks to janea1207 for researching this

I wonder if the depth of the piece you are removing and reinstalling, meaning how far you press it back on when you tap it back on, will affect the calibration if the pressure sensor.

The pressure sensor is on the fuel rail. This only monitors the pumps operation, i.e. the pison movement inside the pump. that's why it's so simple, kind of like a wheel speed sensor. It just monitors movement.

Just did this, thanks for the video. I had to use a hammer on my flathead to get it underneath initially. A couple flick of the wrists later and it was off and I was able to rotate it. You're the man.

Exclamation B58tu pump scratched from connector rotation

I was popping my connector off from the hpfp and I went a little too hard with the flat head and scratched the inside of where the connectors slides on. I'm a bit anxious because I'm not sure if I damaged anything. I put the connector back on and I will install it soon. Hopefully nothing major happens.

I guess in this case you won't know until you try. Good luck with it.

Yup just connected it to my 340 and it worked!
It was a pain to get the fuel line back on but I managed to make it fit.
