i was getting my car tuned a few weeks ago, the pump was purging and not keeping a consistent pressure. its a walbro 255, has anyone else experienced any pump failure like this before? i put a new one in and im getting re-tuned on thursday. BTW it was a stock block 2.2l w/3mm, lovfab mini-me, garret gt3582r, rc 1000cc's, aem ems and we only went to 12psi.

thanks,
-Blake

To help anyone else who might have the same problem, what were the symptoms as far as how it affected the way the engine would run?

the fuel pressure guage was very sporadic. we got a base map at 8lbs and it was fine, then once he went to 12lbs the fuel pressure would plummet. this time it was fine. so just to note that it was definitely the pump.
