Hello,

I saw a few months ago somewhere a thread about building a custom injection pump, it was GQ (Y60) pump with GU(Y61) rotor.
But I can't find it anymore(and I didn't save a link, I was sure I will never need it because of planned TD42 conversion).
I'm also not sure if it was on this forum or somewhere else.

Thread was well documented, also with pictures, I remember something needs to be machined.
There was written that pump with GU rotor can provide more fuel, that was the reason for building a custom pump.

If someone knows what I'm talking about, I will be very happy.
It will save time, and my bosch pumps specialist doesn't need to reinvent the wheel again :)


GU 2.8, with some issues(sometimes after start it idles little higher as normal and NO throttle response, need to start it again a few times. no fault codes logged), want to convert it to mechanical pump.

Regards, Gregor

You actually dont convert the pump it self. Just slap on a mechanical pump from a gq and switch out the injectors

Yes, it is right,
but GQ has 9mm rotor, and GU 11mm and can deliver more fuel.
I found now a similar youtube video:
