BLP Fuel Pumps
INTERNAL BY-PASS FUEL PUMPS
These fuel pumps by-pass the excess fuel internally to the low-pressure side of the fuel pump. The pressure is adjustable at the fuel pump. No regulators of any kind are required or recommended.
ADVANTAGES:
• Easy to install and does not require a return line.
• Easy to adjust and maintain.
DISADVANTAGES:
• Decreased range of pressure from idle to full throttle.
• Recommended to run fuel line as low as possible if trying to utilize rear mounted cell.
• Not recommended for circle track applications when using gas.

.500 WIDE GEAR PUMPS
• Engines using gas up to 850HP.
• Engines using alcohol up to 750HP.
• Tunnel ram set up on gas.
• Marine gas big block.
• Most all circle track and drag application.

500 THICK GEAR PUMP
1800 Pump RPM at 50 PSI flows 108 GPH
2000 Pump RPM at 12 PSI flows 118 GPH
2500 Pump RPM at 12 PSI flows 140 GPH
3000 Pump RPM at 12 PSI flows 168 GPH
3500 Pump RPM at 12 PSI flows 188 GPH
4000 Pump RPM at 12 PSI flows 203 GPH

FUEL PUMP VOLUMES

The validity of advertised fuel pump volumes is only accurate as the method used for testing. In other words, a fuel pump will show more volume if it is gravity fed with no outlet restriction than if the pump had to lift the fuel and maintain a constant pressure. This holds especially true with a mechanical fuel pump.

EXAMPLE: a mechanical pump may pump 108 gallons per hour at 1 pound of pressure but only 60 gallons per hour if it had to maintain 5 pounds of pressure. We test and flow our pumps in a Real world environment. To simulate racing conditions we lift the fuel 18”, pump it through a 1/2” line and maintain race condition fuel pressure.
