HAVE YOU CHECKED THE FUEL LINES WHERE THE FUEL PRIMING PUMP IS CONNECTED FOR ANY CHAFFING THEY ARE COMMON FOR CHAFFING BESIDE THE FUEL FILTER WHICH WOULD EXPLAIN WHY FUEL IS RETURNING TO FUEL TANK.

I need a diagram to show me the routing of the petrol pipes on a citroen c3 from the petrol tank to the engine and back to the petrol tank please?


the fuel is constantly rotating round the fuel lines, the fuel is pressurized, so any fuel that is not used by the injectors is sent back to the tank.. this give a constant flow and pressure to the tank. the pressure in the tank is regulated by the pressure relay that lets air into the tank to lower the pressure. this is regulated by the ecu and your speed. if the pressure drops or is to high in the tank the engine can cut out on the fuel rail there is a fuel pressure regulator this keeps pressure on the fuel line coming into the injection system. some systems have duel line feeds from the tank for 2 rail systems, this system was not reliable due to the amount of feed pressure needed to fuel 2 lines. and can cause pressure leaks. some systems have a pressure regulator controlled by the ecu on the return line, this is more fuel efficient as it keeps the fuel at a steadier flow back to the tank and give a better fuel spray into the engine. hope this help you.

Repaired two fuel lines ,removed sending unit from tank, can't remember which lines go where three lines from engine .


Can you identify or remember which pipe on the sending unit, the pump module, is the main outlet from the pump?
The three lines are the main feed or pressure line to the engine, the return line from the engine to the tank-this line is often smaller than the main line. And the third line is not a fuel line, but the vent line for fumes from the enclosed tank to the charcoal canister. This line may be identifiable by pipe diameter being smaller, or sometimes using rubber hoses with it, or maybe just a little offstanding from the other two lines. The main line (pressure line) will be the line that has the fuel filter in it. You can identify the main line this way, then just figure out where it connects onto the tank, and sort out the other two lines-the return line and the (?smaller?) vent line.

Need to know what 3 lines from fuel tank go


The pump line, or feed line, goes to the fuel filter and then to the engine's fuel rail. A return line leaves the fuel rail and sends gas back to the tank. Usually, the feed line is slightly larger than the return line, not always.
The third line is a vent line for emission controls-routing gas fumes from the tank to the charcoal canister, where it is stored and later sent to the engine to be burned.

Can you down load info and diagram or diagrams on


fuel pump is in the tank try to get most of gas out of tank then you need to unclip pressure line and return line and vent line unplug electric connector and remove tank there usually are no pictures for this if you need pictures you should hire it out

How to change fuel lines


There should be only 2 fuel lines and a vent line coming out of the tank. The vent line is for fumes that are routed to the charcoal canister-part of the evaporative emissions system, and the two fuel lines are the main feed line to the filter and then on to the engine, and the other gas line is the return line from the engine back to the gas tank. All fuel injected systems have a feed line and a return line. The return line is for fuel not used but sent back to the tank by the fuel pressure regulator.
Nowadays, rather than replace metal lines, shops can use the plastic fuel lines (they don't rot!) and special connectors to fit new fuel lines. YouTube has lots of videos on replacing fuel lines.

My gas tank leaks. How do I go about replacing it? It seems to have three fuel lines to the tank. One is a small diameter line and the other two are larger, I am assuming one of these might be a return...


if you take and clamp off the hoses and remove them from the tank,then support the fuel tank,remove the fuel tank holding straps then lower the tank,disconnect the wiring and make sure there is nothing else connected to the fuel tank,remove fuel tank transfer any components to the new tank and re-install.

Vent return,or filter return,by pass.One is a by pass,one is a vent ,to the canister purge.the other is the main pressure line.

Did chevy make a single line fuel pump for a small block


Older chev mechanical pumps had a single feed line. Newer ones had a feed line and a return. The steel lines on the sending unit are feed and return. If there was a vent line it would be a seperate line going to the top of the tank all by itself. If everything is hooked up correctly you should have about 7lbs pressure at the feed line.The needle valve in the carb will not allow leak-back if it is working correctly. If you have a Qjet carb, the bottom bowl plugs sometimes leak... that is a different problem not caused by supply.
