Electric Fuel Pump for carbureted CIH engines
A little background first.
The electric, pulse-type pump (diaphragm, solenoid, points) from an '81 Honda Accord which I've been using on my "Hooters Orange", '72 SSD GT has become somewhat temperamental of late and is not completely reliable any more.
CAN'T really complain about it though, since it ran trouble free for over 240K miles on the Accord and performed without problems for the last 3 years on my GT . . . well, that is until a few weeks ago. Had to go look for a replacement as the timing cover is from an FI engine (no mechanical pump provision).
We all know about the "low pressure/high volume" requirements of the stock Solex and replacement Weber/DellOrto carburetors, but I think it's worth a quick recap to help understand my choice (and recommendation) of a replacement electric pump.
I chose (and can recommend without qualms) a Carter (Federal Mogul) P60504 Gerotor, self-priming, positive displacement pump and mounted it in the well behind the left rear tire. It's small, quiet and will keep the entire fuel line to the carb pressurized to alleviate any potential "vapor lock" problems. The Honda pump was mounted there as well, incidently.
It's a 12V, 2.5-4.5PSI, 30GPH pump, so let's talk about these specs for a moment to allay any fears there may be about it's ability to do the job. Solex, Weber and DellOrto recommend no more than 3-3.5PSI pressure as long as sufficient volume is maintained. They are Low Pressure-High Volume devices.
You might wonder if 30GPH is going to cut it for volume requirements. Let me pose a quick question to put this in complete perspective for you.
Will your engine ever require more than half a gallon per minute? 120MPH is 2 miles per minute and your mileage (engine fuel consumption and pump volume required) would have to be worse than 4MPG for it not to meet these fuel requirements! I DON'T THINK SO!
