Nostrum's Big Bore high pressure fuel pump is a universal HPFP core with a 11.5mm piston and a 250bar operating pressure. This pump is manufactured by Stanadyne Inc. and is capable of 250 bar rail pressure sustained operation, giving this HPFP a much higher pressure rating than the production GM LT4 pump.

Although a very similar outline to a stock GM LT4 pump (part number 12711668 or 12694529), this universal pump differs with an AN06 male threaded low pressure inlet as opposed to a 3/8" SAE quick connect fitting (on the LT4). The AN fitting allows you to adapt the universal pump for your application specific needs with the addition of industry standard AN fitting hardware. This pump does not include the accessories and hardware associated with engine installation. You will need to transfer over the flange, flange bolts, gasket, and secondary outer spring from your existing HPFP.

Piston Diameter: 11.49mm

Max Piston Travel (TDC-BDC): 10mm

Max Operating Pressure (Rail Pressure Target): 250 bar (25 MPa / 3636 psi)

Displaced Flow Per Cam Revolution (6mm Stroke): 1865.44 mm³

High Pressure Fitting Spec: M14x1.0 male thread with inner female cone

Low Pressure Fitting Spec: AN06 male
