I own a 97 1500 ram w/5.2 eng.. My fuel line rusted out. When I took my gas tank off I noticed three lines running along the inside of the frame two of which go to the tank. I want two know where that other very small line connects because on my truck there was only about three feet rusted at both ends.

The filter is an in line filter, probably under the car along the frame rail where the fuel line runs from the gas tank to the engine. There is a bracket and a bolt holding it in place. Follow the fuel line from the tank forward-you should see it.
The fuel pump is inside the gas tank. If you suspect a pump problem because no pressure is in the line or at the injectors, an easy way to check is to see if there is power on the fuel pump wire at the gas tank connector, while the engine is being cranked over. If you have power on the wire then, but no pump sound or gas in the fuel line when the connector is connected, then the pump has failed and needs replaced.

If it is not along the bottom of the frame where your fuel lines run, it is located inside the fuel tank

fuel filter is under vehicle along frame rail, close to driver seat area, it will be a round 3 " long can like filter. Also get some dry gas and put in gas tank to eliminate water in fuel.Put good fuel in vehicle and see if it runs better. It will take a day maybe to notice difference, if nothing changes then look into a tune up

the gas filter is located under the truck on the frame rail (driver`s side) You need a 5/8 line wrench for the gas lines, along with a 13/16 or 21mm wrench for the gas filter. Hold either wrench and turn counter clock-wise. You may have to soak the filter and lines with penatrating oil to loosen it up. Make sure you where saftey glasses and don`t even think about smoking..
As for draining the tank, that is more difficult-you will have to drop the gas tank and tank support straps. Not something you want to do at home.A lift hoist will be more safer and the proper way of removing the gas tank. If you are draining the gas because it`s old, I would just run it through with fresh gas added. this will save you fustration..Or to drop the tank-go see your repair shop for this service. Remember gas is very dangerous and expensive too, if you don`t know what your doing.-leave it to us pro`s to do the job right the first time. I guarantee the lines , straps, and filter will be very rusted, and will give the mechanic some difficulty preforming this repair due to the age of your truck...

Your fuel lines run along passenger side frame rail. From the fuel tank over axle and along inside of frame rail (pass side)

Your gas tank is in the back of your car between the frame rails. The fuel line runs up toward the engine along the drivers side frame rail on the inside of the frame rail. The fuel filter is located along that fuel line inside the drivers side frame rail, about at the back of your front door. You should be able to trace the fuel line all the way to the intake of your engine. Once you locate the fuel filter, you will need a special tool to remove the filter from the line. You should be able to get the 'fuel filter tool' at your local auto parts store for under $10. The tool has a flanged end on it, and it 'scissors' open and closed. Place the proper sized end on your fuel line just in front of the filter so that the flange sticks in toward the filter. Gently push the tool in toward the filter, while pulling back on the fuel line. The line should come disconnected. Remember, the fuel line is pressurized and may spray gas for a second or two when it comes apart. Then do the same to the other end of the fuel line. Good luck. Any problems, write back.

It would not,there is a fuel line that runs back to the tank along the frame of the car,and the line is most likely leaking

The Lines are simple if it's a 2.4 EFI the lines run on the driver side inner rail from the center top of fuel tank, and up the middle of the firewall to the injector rail or throttle body carburetor there is also one line that runs from the evap canister back to the tank and to the fuel system three lines total one is a return line the large line is the main fuel line and has the fuel filter mounted on it and is under the driver side door inside the frame rail.

Probably a leak in the flexible line that connects the pump to the metal line. Or the pump itself.

as an owner of three gmc sierras, i can attest that the brake lines that run along the frame rail under the master cylinder inherently rust away and break. I wouldnt neccesarily think it was tampered with. but do check the condition of all of the lines including the fuel lines for excessive rust.
