How To Test Low Pressure Fuel System On Direct Injected Cars Like MK6 GTI

How To Test Low Pressure Fuel System On Direct Injected Cars that don't have a low side pressure sensor like the MK6 GTI, MazdaSpeed3, MK7 GTI, Subaru WRX, etc.

When are you guys gonna do a dsg tune for the mk6

[@KAS470]

When Cobb releases tcu tuning for the mk6

[@fausto5733]

Hey nice video. Wondering what the low side pressure should be at idle cause mine is bouncing from like 79 to 85. Thanks

[@stratifiedauto]

This is about right. You will get some fluctuations.

[@surfjujitsu2456]

Is there a link to this kit pretty cool kit

[@stratifiedauto]

This is a fuel pressure test kit from Amazon and a ram suction cup mount.

My fuel rail connects to the hpfp with a stiff aluminum fuel line. Do I connect the gauge straight to the hpfp? There's nowhere else to connect it

[@stratifiedauto]

You don’t want to connect it between the fuel rail and HPFP as that is high pressure. You want to connect it between the fuel tank and HPFP. This should be a soft line coming into the engine bay.

What's the minimum pressure for the electric fuel pump on a GTI MK5 2.0 TFSI? 6 bar fuel pump?

[@stratifiedauto]

I wouldn’t want it below 40psi at wide open throttle.

[@jesealanis2309]

My 2015 gli low pressure is at 50 while steady speed then drops to 45 psi when I get the torque limitation code

[@stratifiedauto]

The code and fuel pressure are probably not related.

[@lirimhas1622]

I had the fuel pressure on 40bar on idle, 2 days later on low rpm the engine stalled and now it is at tje mechanic. No fault code what so ever, suspecting it is the lpfp and fuel filter. golf 6 gti

[@stratifiedauto]

You can check the LPFP like it do shown in the video.

@@stratifiedauto Thanks, i let the mechanic know so he can start from there and save him from hassle.

[@lirimhas1622]

@@stratifiedautoSo, i've got the car back from VW dealership. I see that the engine is filled and mixed oil with petrol. What could cause this? Is it from trying to crank it up and start it without luck?

[@stratifiedauto]

I have seen stuck op e injectors on these motors.

[@modifiedmillennials2382]

Hey I was wondering what’s the spec for a mk6 gti low side pressure

[@stratifiedauto]

That depends on engine rpm and load. Under wide open throttle it should not drop below 45psi

[@thejaydot5194]

What’s the pressure reading for 2017 gli?

[@stratifiedauto]

This will depend on the demand on the fuel system. You want to see above 50psi at wide open throttle.

@@stratifiedauto HI i have a CC 3.6 ,what's the LOW/HIGH fuel pressure reading for it ?

[@bleach_drink_me]

Any idea what max whp will be for a stock fuel system mk6 gti with a snow stage 2.5 WMI kit with a #6 nozzle running 1:1 water:meth.
I know it's not possible to give an exact number but a ball park would be welcomed. I would do this test but my engine is out of the car waiting on parts.
I have maxed out a f23t on stock fuel with wmi and logs never showed it lean, at times i even saw afr in the 10:1 range(yes tune needed some adjustments). Looking for the next step up in power in the near future.

[@stratifiedauto]

F23t maxes out in the upper 300whp range.

[@wyattayre1465]

I have 3 codes on rn if anyone knows if it’s a sensor or the actual fuel pump? My codes are
P2293
P053f
P0087
Lmk if you know anything low fuel pressure
