How do I blow out the fuel line?

The fuel line runs from the gas tank (underneath) the car up to the injection rail on the engine. Since most of the fuel line is inaccessible, trying to thaw it with a hair dryer is not a good option. You could try blowing the hair dryer on the fuel filter. A better option is to get a couple bottles of HEET at your local auto parts store. Put this in the gas tank. If the fuel line is completely frozen, HEET is not likely to work. You will need to bring the vehicle inside a warm shop. If the problem is water in the fuel, HEET will prevent it from freezing in the future. A gas line will not freeze, unless there is contamination in the fuel. A fuel filter change is a must in this situation, and may solve the problem.

You are going to have to drop the tank and replace the fuel pump/module assy. Once removed you can blow out the lines and replace the filter.

FUEL PUMP MORE LIKELY WORN OUT SHORT OUT.BESURE REPLACE FUEL PUMP WIRES IF FUEL PUMP HAS TO BE REPLACED.CODE SCAN FOR ECU FAULT. IF FUEL FILTER STOPPED UP FUEL PUMP WILL SHORT OUT.

probally rust in the tank that's clogged the pickup filter in the tank or the fuel filter. or if you're in a cold climate, gas could be frozen too.

blow it backwards with a air line ,disconnect the pipe at the tank end and blow back from the engine end ,acetone will disolve anything ,but blow fuel line with air the pour some acetone down it ,leave it for a couple of hours then blow airline again

you need to remove the fuel tank and have it cleaned, radiator shops can do this.

fuel pressure regulator is bad or there is blockage in the lines

You hit the nail on the head. Chances are the sending unit filter "sock" is clogged. Most of the time you can clear it by blowing compressed air back through the tank.
I would however, inspect the suction line from the fuel pump to the tank for rust obstruction and hoses for de-lamination.
Disconnect the line just before it goes into the tank and try to blow air through it just to make sure it is not rusted shut.
Good luck, let me know.

Hi!
How's the fuel lines/system? looks like you may have a blocked line or fuel filter as the pump needs to continue running and if no circulation back to tank safety procedures kick in i.e. fuse blow.
Hope this helps?

Sounds like the PCV valve might be clogged and has created a vacuum within the fuel line. A new valve will cost you about $15.00 US and is easily replaced. You will find it on the top of the valve cover, depending on the engine model you have.

You should also check the fuel pump and verify that it too does not have a vacuum and therefore is not drawing gas from the tank. The fuel pump is located inside of the trunk. When you turn the key to the on position, have someone listen inside of the trunk for the faint sound of a motor come on. If you hear the pump engage, then you might have a blockage within the fuel line.

To fix a physical block in the fuel line you will need an air compressor and a blower nozzle that will fit inside of the fuel line. To blow the fuel lines out, begin by removing the fuel line from the fuel pump at the tank, then remove the line from the backside of the fuel filter. Place the end of the fuel line that was detached from the fuel pump into a large bucket and somehow tape it in place so that it will not blow out of the bucket when you go to blow it out. Now take the compressor air nozzle and insert it into the fuel line that you detached from the fuel filter and GENTLY begin blowing air into the line and have someone watch the other end in the bucket.

Once you have air flowing freely through the fuel line, reattach everything and fill the tank with fuel (if it's still empty) and try starting the engine again. If you still have the stalling problem, more than likely the fuel pump is shot and will need to be replaced.

Hope this helps you out.
