[FC] In-tank fuel pump

[Jim Davis]

The Corvair gasoline heater is rated at one quart of fuel per hour to 
produce a heat output of 30,000 btu.    Because of the high temperature 
limit switch, the heater will not operate on a grater than a 70 % duty 
cycle even at temperatures of zero degrees F.   Assuming one was driving 
60 mph and getting 20 mph that would equate to a 2.3 mpg decrease.  I 
find the use of the gasoline heater in the Rampside at ambient around 20 
degrees F will drop the highway mileage by 1.5 mpg and about 2 mpg 
around town.
