Fuel line help 97 grand marquis Sign In

Year of vehicle- 1997
Make of vehicle- mercury
Model of vehicle- Grand Marquis
Engine size - 4.6 8 cylinder
Mileage/Kilometers-140k Miles

Hi i'm looking for help replacing the back fuel lines. im not very savvy with auto repair. can you tell me if this is a doable, at home, repair?

If so can you tell me all of what ill need to replace the whole lines, or even the broken/leaking segment?

Mind you i am on a budget, or i would take the car into the shop which is an estimate of 180+35 for towing.

Thanks i would really appreciate some general instructions and general tools i would need and the kind of lines/ line kit to buy. I really want to learn how to repair my own car.

It is doable. You just have to cut out the bad pieces or you can fashion a whole new line. You'll need a tubing cutter, flaring kit, tubing bender, steel line that is the same size, and fittings to join pieces together. If you have to connect couplers, connect braided line pieces, or connect nylon to steel line that is when it gets more involved and requires special equipment.

If you have never done it before, you should practice making flares and bending line. Have your work inspected by a professional to be sure it is done correctly.

Don't ever use compression fittings on brake lines.

You've been around here long enough to know you can't post links.

Re: Fuel line help 97 grand marquis Sign In

can you message me that link?

And also my dad said since my car is fuel injected that the lines are high pressure or pressurized. How does that effect the job? Do i need to depressurize the lines first?

Links that lead to other sites are not allowed on open posts. What folks do with the private messages is fine. The idea is it's a free to use site so promoting another doesn't fly.

This job may not be for you. The parts are not frightfully expensive, tools fairly reasonable to own. Already said you should practice on some extra line and use legal connections. You flare lines and use unions not the compression fittings for some other things entirely.

The replacement line must also be fastened back in place, not rubbing but done as it was routed originally. The potential for messing up the job is always there but doing fuel or brake line work wrong is potentially a disaster.

Not to discourage anyone to learn and do things. This one should be done by a shop in no time and you'd be back in your car without the hassle. Some are. Up to you of course just do it right,

Re: Fuel line help 97 grand marquis Sign In

and to answer your question the fuel system is under high pressure (around 50 psi). If you do go to replace an item in the fuel system, you have to depressurize the system.

Easiest way I found is to remove the fuel pump relay while the engine is running. When the engine stalls out the system should be depressurized. Disconnect the battery when working on the fuel system. No smoking and sparks around the gas tank. Keep a fire extinguisher near by. Use common sense. There will be some residue pressure when you go to open the system up, but nothing like a fully pressurized system.

It you're re[placing that line due to a leak, then I doubt there will be any pressure left in it anyway.
