Fuel leak only when cold below the fuel filter rear. tried to clamp hose but leak still there somewhere behind the hose connector.

Paul; You probably have found the leak, which was a repair made by somebody else in the past. Ensure leak, rusted out, or crack is cut out of steel line before making below repair and follow all safety precaution when working around flammable fuels.
To do a cheap repair which is not necessarily the best remove and replace existing hose and clamps. Go get a length, enough (high pressure) rubber fuel hose, (4 gear clamps) to put over hose to double clamp connections on both ends of hose. This repair could last the life of the car easily.

Fuel Line Leak Quick Cheap Fix

Fixing Fuel Line

I know the feeling well when this happens. I to did the same as you and also did the clamp, but found the best way was to yous a crimp tool for fuel lines and its not come off since its like the tool to put brake lines on to the calipers and then you put the rubber hose onto it and using a fuel line clip to hold the rubber in place. has lasted the last 5 years now with no problems.

Is the leaking at the fuel filter, or somewhere else?
Did you replace the rubber hoses on both sides of the filter? If not, check to see if they broke when you pulled old filter, replace any that did.
Did any old rubber stick to the metal pipes, when you pulled out the old hoses? That can keep new hoses from sealing, even with good torque on hose clamps.
Make sure your hose clamps are tightened properly, with some bulging rubber at the openings in the clamp, but not cutting the rubber into ribbons. It is possible to over-tighten hose clamps, and shred hose rubber. If you see ribbons of hose rubber sticking up out of the metal clamp you have done that. Replace the hose, and the clamps, and make sure the metal pipe is clean, before you carefully tighten the clamps.

The FSM is clear on this. each hose and fitting must be air tight.
or the the car vents gas fumes full time, and the EVAP ECU tests
(monitor) make sure this all works.
you can just look at the left and right side above rear tires. and see
if your hands are small enough to fit here. Id bet not.
some mech, report, the tank can be tilted down at front (drained fuel)
and gain access.
keep in mind, you get fuel siphoning at any time. do not open the system, with fuel in the tank, and then drive to autozone,
i loosen the gas cap so that pressure can not build in tank.
expanding fuel can push fuel out , during a filter change. very
dangerous in a garage, and you gone.
it's just a vent hose, you can see, it and what needs to be done is really obvious. given you arms sides and lenght.
my fsm states, " TANK pull"

Removal & Installation

1. Relieve the fuel system pressure and disconnect the negative battery cable.
   
2. Remove the fuel filler cap from the fuel tank.
   
3. Have a Class B fire extinguisher near the work area. Use a hand operated pump device to drain as much fuel through the fuel filler neck as possible.
   
4. Use a siphon to remove the remainder of the fuel in the tank by connecting the siphon to the fuel pump outlet fitting.
   CAUTION Never drain or store fuel in an open container because there is the possibility of a fire or an explosion.
   
5. Reinstall the fuel filler cap.
   
6. Remove the rear seat cushion from vehicle (if so equipped).
   
7. Disconnect the fuel pump motor connector and sending unit electrical connectors.
   
8. Disconnect the wire harness grommet and harness through the vehicle floor pan.
   
9. Raise and safely support the vehicle.

11. Remove the fuel breather hose clamp from the filler neck assembly.
    
12. Remove the fuel filter inlet hose clamp and hose from the filter.
    NOTE A small amount of fuel may be released after the fuel hose is disconnected. In order to reduce the chance of personal injury, cover the fitting to be disconnected with a shop towel.
    
13. Remove the fuel vapor clamp and hose, and fuel return hose clamps and hose from the respective fuel lines.
    
14. Using a suitable transaxle jack, support the fuel tank.
    
15. Remove the fuel tank retaining bolts and lower the tank.
    

To install:

1. Reconnect all fuel hoses, lines and the fuel breather hose to the fuel tank.

You can check to see if the hose clamps are tight on the filler neck and the breather hose ,i would also check the fuel filter under the car rear near tank for leak's as this can give the smell of fuel around the rear of the car . when you open the boot of the car do you smell fuel or is it only on the outside of your car????? hose clamps and fuel filter = outside of car. smell in side of trunk (boot ) fuel return line hose clamp might just need to be tightened up. you might have to remove the rear wheel and inner wheel cover to get to the Fuel tank filler to check the hose clamps.

The fuel filter is located under the rear seat.
Fuel Filter Replacement:

1. Reduce the internal pressure of the fuel lines and hoses by completing the following operations:
   • After removing the rear seat cushion, disconnect the fuel pump harness.
   • Start the engine. Allow it to stop by itself, then turn the ignition switch OFF .
   • Disconnect the battery negative (-) terminal.
   • Connect the fuel pump harness connector.
   
   
2. Remove the eye bolts while holding the fuel filter nuts securely.
3. CAUTION: Cover the fuel filter with a shop towel to avoid residual gasoline from splashing.
4. Remove the fuel filter mounting bolts, then remove the fuel filter from the fuel filter clamp.
5. After replacing the fuel filter, check for fuel leaks.

Fuel Filter REMOVAL & INSTALLATION CAUTION
NEVER SMOKE WHEN WORKING AROUND OR NEAR GASOLINE! MAKE SURE THAT THERE IS NO ACTIVE IGNITION SOURCE NEAR YOUR WORK AREA! 1970-83 Carbureted Engines The fuel filter is located on the right inner fender in the engine compartment. It is a disposable cartridge type.

1. Using a pair of pliers, expand the hose clamp on one side of the filter, and slide the clamp further down the hose, past the point to which the filter pipe extends. Remove the other clamp in the same manner.
2. Grasp the hoses near the ends and twist them gently to pull them free from the filter pipes.
3. Pull the filter from the clip and discard.
4. Install the new filter into the clip. Push the hoses onto the filter pipes, and slide the clamps back into position. Start the engine and check for leaks. Fig. 1: Fuel filter - 1970-79

1984-86 Carbureted Engines The fuel filter is located on the inside of the frame above the left rear spring front shackle. Changing the filter is VERY awkward. Since it is in-line and below tank level, fuel will pour from the fuel lines when they are disconnected from the filter. The only way of preventing this, is to siphon all of the gasoline from the tank before replacing the filter. Another possible method is to clamp and plug the fuel line, but this is not recommended because of the danger of leaking fuel or damage which could occur to the fuel line when clamped. It would, therefore, be a good idea to run the tank almost dry before changing the filter. Once the tank is dry, disconnect the fuel lines at the filter, unbolt the old filter and install a new one. Reconnect the fuel lines, fill the tank, start the engine and check for leaks. Fig. 3: Fuel filter - 1984-86

Fuel Injected Engines WARNING
Never attempt to remove the fuel filter without first relieving the fuel system pressure!

1. Release the fuel pressure from the fuel line as follows:
   1. Remove the fuel pump fuse at the fuse box.
   2. Start the engine.
   3. After the engine stalls, crank the engine two or three times to make sure that the fuel pressure is released.
   4. Turn the ignition switch OFF and reinstall the fuel pump fuse.
2. Loosen the hose clamps at the fuel inlet and outlet lines then slide each line off the filter nipples.
3. Remove the fuel filter.
4. Replace the fuel filter. Always be sure to use new hose clamps. Fig. 7: Fuel filter - 1986-88 VG30i

Hi,

CAUTION
If equipped with an Electronic Fuel Injected (EFI) engine, you must first release the fuel system pressure, before removing the fuel filter.

The fuel filter on all models is a disposable plastic unit, located at the rear of the engine compartment. The filter should be replaced at least every 24,000 miles (38,647 km). A dirty filter will starve the engine and cause poor running.

It's the little one, in this diagram:


Locate the fuel filter on the left (driver's) side of the engine compartment. Place a container under the filter to catch the excess fuel.

1. Loosen the hose clamps, then disconnect the inlet and outlet hoses from the fuel filter. Make certain that the inlet hose (bottom) doesn't fall below the fuel tank level or gasoline will drain out.
2. Pry the fuel filter from its clip and replace the assembly.
3. Position new hose clamps, if necessary, then connect the inlet and outlet lines. Make sure that the closest edge of each hose clamp is 1⁄8 in. (3mm) from the end of the hose before tightening. NOTE: Ensure that the screw does not contact adjacent parts.
   
4. Start the engine and check for leaks
