The weak point the the L67's fuel system is a much simpler fix than you would suspect: the wiring. On cars running high flow fuel pumps, the stock wiring is unable to carry enough current to keep the pump flowing at capacity, resulting in high resistance and a possible fire hazard. The fix is Caspers Electronic's Plug & Play "Hotwire" fuel pump kit. No wire cutting involved, this kit is a quick step to better pump performance.

 

 

 

 

 

 

A note for those running 255lph fuel pumps - We strongly recommend the use of this kit for those running any variation of the 255lph fuel pumps available on the market.
