No, Only the supply line has to be submerged in fuel.
need to no the fuel delivery line on 89 chevy truck fuel pump
No, there is no return line. Because of the low pressure of fuel systems on carberated vehicles, there is no need for a return line.
A fuel return line should flow freely back to the tank. There may be a check valve on the fuel return line that prevents backflow from the tank to the regulator.
need photo of return fuel line off motor from a 89' toyota p.u.4x4 with a 22RE motor
I am going to say yes for safety sake, only because if you had a blockage somewhere it could blow open.
Check to see if your return fuel line is pinched. If so chenga it and all your troubles will go away
You'll need to reair the fuel line by replacing the fuel line .

On a 2000 Jeep Cherokee Sport, the fuel return line is typically located along the fuel rail on the engine. It runs from the fuel pressure regulator back to the fuel tank. You can find it attached to the fuel rail, usually on the passenger side of the engine. For specific access, you may need to lift the vehicle or remove components in the engine bay for better visibility.
You need to take it to a repair shop that has the equipment to properly repair it.
It depends on what you mean By How Many. If you mean how many difrent parts make up the fuel lines I need to know Year, Transmission and Engine type. If you mean fuel line assemblies there are two. Presure line from tank to fuel injection and Low pressure return line to tank. There are several other lines that look like fuel lines that are for the fuel tank vapours.
You'll have a total of three fuel lines associated with this saw. The line, in the tank, with the fuel filter attached goes to the fuel pump side fitting of the carburetor. The line, in the tank, that is about only an inch or so in the tank is the return line and originates at the "out" nipple of the primer bulb. And the third and last line goes from the "in" nipple of the primer bulb to the carburetor fitting furthest away from the fuel pump side. Note that the fuel pump side of the carburetor is the side that integrates the throttle idle speed screw." That return fuel line is a booger if you don't have to replace the main fuel line. The orifice is hidden from view UNDER the hole for the main line. However, I got it replaced and the old McCulloch works fine again.
