Hi Victor, I'm glad to help! Victor, my first suggestion is to call the dealership with your VIN Number and see if they have a RECALL for you vehicle for fuel leaks. If they do then you can get it repaired and it won't cost you anything. If its doesn't have a recall then you'll need to replace the part that is leaking. Hope this helps and have an awesome day Victor!

SOURCE: 98 Expedition coolant leak top back of engin

Sorry im late with this,i couldnt seem to log on....The answer to your question is YES,there is a steel line under the intake with a short piece of rubber line attached to it and you can just about see it from the front of the intake with a light,it can leak and cause coolant to run off the back of the engine,The intake gasket set alone is about $40.00 and i dont know about the rubber line,i have seen it physically but havent changed one yet.Note the date of manufactor just incase,i bought an intake set for a 99 and the engine design was changed half way through...its not too hard to pull off the intake and re-install,you will need a 7mm socket for the coil packs,8mm socket for the fuel rail bolts and lower intake bolts and power steering bracket bolts and throttle bracket bolts,10mm socket for the intake bolts and alternator bolts and egr valve,and a large cresant wrench for the exhaust tube thats connected to the egr valve,flat screw driver for the air cleaner...and plenty of extensions with a swivel to be able to get to the back bolts of the intake....just incase you do it yourself this info could make it easier to gather tools.Its about a 3 1\2 to 4 hour job start to finish for the first time doing it,includes cleaning everything..Good luck

SOURCE: fuel leak under turbo on 1997 ford 7.3

Is the fuel in the valley right under the fuel pump? If so, your fuel pump might have failed and is leaking out of the weep hole.

Other places to look would be the fuel filter seal and a bad o-ring in the fuel drain relief valve.

Good luck

Rough idle and misfire


These trucks have a spider injector and all depending on the year it may have one central injector or 6 and then popets, these are lines that run to each injector, you will need to make sure the fuel pressure is good, low pressure will cause problems i think it is 62 psi key on engine off, and the other problem is the fuel lines going into the rear of the intake to feed the injector leak inside and cause rough idle and misfire, this is for the older one. the newwer trucks have the fuel lines external and you will see them on the top of the injector housing.

A good way to tell if the line is leaking , o and also the fuel regulator inside the plenium also leaks causing the same type of problem, to test you will need a fuel pressure gauge , hook it up ,turn key on and pressure will go up then turn key off and if pressure drops then you have a leak, could be fuel pump check valve but may be line or regulator, if you remove the throttle body and with a pen light look inside intake for leakage.or remove upper intake and do the same thing, better view this way.

P0442 - Evaporative Emissions System Leak Detected (Small Leak)

P0455 - Evaporative Emissions System Leak Detected (Gross Leak)

This diagnosis detects leaks in the EVAP purge line using engine intake manifold vacuum. If pressure does not increase, the ECM will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition. The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.

Causes:
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve
- Leak is in line between intake manifold

Solutions:
- Re-tighten or replace fuel tank filler cap
- Replace damaged or leaking EVAP canister
- Replace damaged or leaking lines.

I have vacum leak on top left side of my engine as if u were standing on the passengers side of the car its a hose that goes in between the 4th and 6th fuel injector, right underneath were the fuel lines...


If the hose itself is leaking replace the hose. If its the plastic fitting, remove the hose, remove the plastic fitting from the intake (should clip in), replace the o-ring on the fitting, reinstall the fitting into the intake, and install the hose onto the fitting.

When you turn the key on excessive fuel flows into the air intake. its a 1989 6 cylinder 3.1 fuel injected


You could have either an injector that is stuck open or a fuel pressure regulator that has developed a leak. A leaky injector will usually only leak fuel into one cylinder as it is located just above the intake valve in the lower part of the intake while a leaky fuel pressure regulator will leak fuel into the front end of the intake manifold [behind the throttle plates] and the fuel will acuumulate throughout the upper intake plenum. When a fuel pressure regulator develops a leak the fuel that is escaping from it flows through the small 1/8" diameter plastic vacuum line which goes from the top of the regulator to the intake manifold. Even a trace of fuel in this line means the regulator is bad. I've seen both leak items leak but probably replace 10 regulators leak for every one injector. Good luck, hope you find your problem!

#3 CYLINDER IS FULL OF FEUL AND TRUCK WILL NOT START.REMOVED SPARK PLUGS AND GAS POURS ON GROUND WHEN KEY IS TURNED ON FROM #3 CYLINDER PLUG HOLE.


The Vortec engines were notorious for those kind of problems. The problem will be under the upper-intake manifold, and the fuel injector assembly will either have a cracked plastic fuel line running out to one or more of the fuel injectors, or the fuel pressure regulator that is located on the end of the fuel injector assembly is faulty or it has detached from the fuel injector assembly. Either way the lower intake manifold will be flooded with fuel anytime that the fuel pump runs.

There were two types made, the first type had fuel lines that connected to the lower intake manifold, and then from the metal fittings the fuel line turns into plastic and runs inside the lower intake manifold and under the upper-intake manifold where it runs over to the fuel injector assembly, and this type can really flood out an engine when it becomes faulty.

The second type had metal fuel lines running over the upper intake manifold and they connected to the top of the fuel injector assembly, however, under the upper-intake manifold there are still plastic lines to the fuel injectors and also the fuel pressure regulator that could be faulty and cause the engine to severely flood.

The upper-intake manifold is not that difficult to remove, and after you remove the upper-intake manifold then (replace the fuel lines to the fuel injector assembly if it is the second type) turn the ignition to the "Run" position and when the fuel pump runs you should see where the fuel is leaking/spraying from, and it will most likely be a large high pressure leak from a ruptured plastic fuel line.

Let me know if you require any further assistance.

It doesn't want to start when its sat for over 5 hours. But if I turn the key to the on position 4 or 5 times to run the fuel pump it will start. What could cause this problem? Thanks steve


Most likely fuel pressure regulator or injectors under intake plenum leaking fuel. Remove intake plenum look for washed down intake. It will visibly be clean & no carbon build-up. Energize fuel rail. With plenum off, reattach fuel line. Turn key to run. Watch for fuel leaking in back (fuel pressure regulator) or out nylon lines (fuel injectors). Very common problem.

You may need a tune up, spark plugs and plug wires. I would also consider replacing the fuel filter, if it has been replaced. Also check the air filter.
