Hi Guys,

Ive got the ST170 engine in my Mev Rocket and im having similar issues high RPM hesitation with no engine light or faults logged on the ECU.
The issues only happen when the car is in motion but are fine when stationary and revs up to the limiter.
I changed the coil first and the IMRC appears to be working fine.

Does anyone know of any replacement or uprated pumps that i can just change in the sender unit rather than changing the whole thing at a ford price of around £240!

Was looking at something like:
