I believe you are asking about a fuel pump and fuel storage cell used to supply gasoline to an engine, perhaps in a car or other vehicle. If not, the answer below is wrong... The fuel pump can usually supply fuel at a much greater rate than the engine can use. In a carbureted engine, when the float bowl is full, the float and needle valve reduces fuel flow so as not to flood the engine. If the engine is idling or cruising with not much load, there is very little fuel flow to the carburetor. Most of the fuel just sits there in the line. If the temperature is high enough, like under the hood of a car sitting in traffic on a hot summer day, the stagnant fuel in the line can boil, causing vapor lock and a stalled engine. This is why we add a return line. Instead of just sitting there in the line, excess fuel flows through the bypass line back to the tank, where it mixes with the large volume of fuel in the tank, cooling it. The fuel circulating through the system never (hopefully) gets hot enough to cause problems. If the engine is fuel-injected instead, then the return line also serves another purpose. The pump sends fuel to the injector fuel rail, then the bypass line returns it to the tank. The fuel pressure regulator adjusts the amount of fuel returned through the return line to control the pressure in the fuel rail so the injectors have a constant pressure to operate from.
Doesn't have an electric fuel pump. It has a mechanical fuel pump and it is attached to the engine. Follow the fuel line from the carburetor, it will lead you right to the pump.
fuel return line is basically used when the injectors does not require more furl in them to inject inside the combustion champer.. so the extra fuel goes back into the reservoir tank through over flow bypass line..
its in the gas tank with the electric fuel pump
Follow the fuel line from the fuel tank to the engine. If you do not locate an electric or mechanical fuel pump, it is in the fuel tank.
Could be any of these: Bad fuel pump, blown fuse or broken wire (if you have an electric pump), dirty fuel filter, blocked fuel line, fuel line leaking, no gas in the tank.
Yes you can. Just run a piece of rubber fuel injection hose from the fuel pressure regulator outlet to the main fuel line that runs to the fuel rail and clamp it... Or you can use a fuel line from a late '98 or '99 Neon from the junkyard that way you will have quick disconnects.
Including electric vehicles, the Smart line of cars have the best fuel economy, at a combined rating of 107mpg. Not including electric or hybrid, the Scion iQ has the best fuel economy at 37 mpg.
Yes I do it for demo derby cars when I use a fuel cell
Either on top and inside the fuel tank on fuel injected vehicle or on the engine block of vehicles with a carburetor. There are a few vehicles with carburetor that have an electric fuel pump. To find it just follow the fuel line to the engine. You will run into the fuel pump.
it will work but you have to use a pressure regulator in line so you can set the fuel pressure down to 6 psi. for the carburetor
Its a pressurised system it will run till you turn the key back off.
Find a good place to mount the electric pump, like an inner fender well or fire wall. Find a good ground for the black wire and run the red power wire to an ignition point in your fuse box. Remove the input line from your mechanical fuel pump and cut off the threaded part. Run a rubber fuel line from there to the input of the electric pump. At the carb. cut your input line about 2 inches back from the carb. then run another rubber fuel line from there to the output of the electric pump. Be sure to clamp all rubber lines good and tight and don't run them near engine parts that get hot. Also be sure to leave your mechanical pump installed.
