At what point would you say i needed to put a group A pump on my 2wd cossy on greys ,hybrid,etc all the usual spec recently had a new pump fitted and the wiring re-newd to the correct voltages just wondered at what point was needed before i have it live mapped ?

 

I'd put it on straight after anything after greens, you can never be too careful with fuel delivery £150 for a decent pump is better than £3000 engine rebuild imo
