...2001, pickup, 4 cylinder? I have a Chevy s10, 2001, pickup with a 4 cylinder engine. It uses a flex fuel pump, which I am changing.
The new fuel pump that I just bought on Ebay has no instructions and no markers on it's 3 fuel connectors except for the following: 1 connector, the one on the left side, has a larger diameter than the other 2 (this should be easy to connect, since only one hose is larger). The other 2 connector's have the same diameter, and the connector on the far right side has a green dot on it.
From what I can tell, there is a fuel line that connects to the fuel-filter. This fuel filter is cylinder shaped and also has 3 connectors. One connector is on one side and 2 are on the other.
Also, there is a large box attached to the chassy near the fuel tank that has a fuel line that attaches somewhere on the fuel pump.
So to sum it up, these are the 3 fuel connectors: 1 to the big box (charcoal box?), 1 to feed the engine, and a return line from the engine.
So how is all this supposed to connect together?
Will looking inside the fuel-pump assembly give any clues?
What's the green mark stand for? Could that mean that that connector is supposed to be attached to the box?
How is it all supposed to work? One line pumps gas through the fuel-filter to the engine. One line returns gas that is not used from the engine to the fuel-tank (using the fuel pump as a bypass), and another line connects to ? And why does the fuel-filter even have 3 connectors?
