The 255 is way overkill for NA (I'm running one boosted)... 450 would require invasive modifications to the stock pump basket and may even require adding a return system system if the OEM regulator can't be drilled enough to handle it, or the OEM filter has to be cut away to accommodate the pump itself. Too much overkill

OP - it could be a broken basket tophat and not the pump itself. CJM sells an aluminum replacement tophat - the dealership will want you to buy a whole new pump basket assembly - which also carries the risk of breaking again in the future.

Rusty and SRJ like this.
