Corvair In-Tank Pump

This is a Stainless Steel Corvair sending unit mounted to an electric turbine pump used in most 1970-80s in-tank pumps. The pump design is well tested and proven and we take great care in manufacturing these units.

  • Our units have the following features:
  • Premium Turbine type Fuel Pump rated at 3-6 psi
  • Nylon convoluted fuel hose
  • Viton seals used on Power Stud
  • PTFE fuel-safe electrical wire
  • New Filter Included
  • New Seal and Ring Included
  • All electrical connections are crimped and soldered
  • A 1/4″ male stud and insulated slip-on terminal provided

We offer EM (61-64), Late (65-69), and FC Models.

Why an Internal Pump? These pumps are mounted on the end of the sending unit and are submerged in fuel which keeps the pump cool and reduces noise. They are highly dependable and will most likely outlast the car. External pumps can be noisy and can usually be overheard at idle and emulate a mechanical pump “The Clunk-Clunk noise”.  The internal pump uses a turbine and does not create fuel pulses that might improperly force the carb float open. 

 Finding a mechanical fuel pump that doesn’t leak or fail is becoming impossible and we think this is a good, long-term solution.

You should check the gauge calibration and operation of the sending unit against your gauge before installation.  We test every sending unit for the proper Ohms before modification.  MOST GAUGE FAILURES are ground-related… so check your ground while testing and installing.  You must specify early or late as they have different gauge Ohms.

This pump assembly will work on any Carburated Corvair.  You may also add a pressure regulator according to your needs..most Carbs do not.

We lubricate and test-run each pump before it leaves our shop as part of the quality control process.  DO NOT RUN THE PUMP DRY.  The nylon convoluted hose between the unit and pump is impervious to today’s fuels.  Do not tighten the electrical connection as the brass screws with lock washers will break off and are also not covered under warranty.

YOU MUST USE A FUSE BETWEEN THE PUMP CONNECTION AND THE FUEL PUMP RELAY!!!
