The high performance Walbro 255 fuel pump has a flow rate of 255 liters per hour at 40 psi and can achieve a maximum pressure of 8.5 bars (120 psi).   (the factory pump is 190 ltr/hr for comparison).
 
This high flow pump operates on a 12VDC system and is an in-tank, gasoline-compatible fuel pump. Key specs include an 8.9 amp draw at 40 psi and the ability to support up to 500-650 hp with gasoline.    This is the high pressure, high volume pump and is a genuine Walbro/TI Automotive pump - made in the USA.   Beware as there are many overseas knock-off pumps out there!
 
This is the *complete* pump, hanger, and new fuel sending unit assembly and is a drop in fit for any L body turbo car.  Specifically, Omni, Charger, and Rampage.    Note that if you install this pump into your Shelby Charger, Charger GLHS, Omni GLH turbo, or Omni GLHS, along with a stock fuel pressure regulator mounted on your fuel rail, you will achieve the factory 50psi (with vac line connected) and approx 55-58psi with vac line disconnected (which is stock pressure).  However, at that stock pressure, you will be flowing considerably more fuel volume at that same pressure.  (vs the stock pump)
 
 If you are looking to modify your turbocharged L-body...this is the pump you want!!   It will support big power, and is a beautiful (complete) drop-in pump and sending unit!
