To whom ever can point me in the right Direction:

I have 1995 Ford F-150 4x4 with a 5.8 L engine. The problem I'm having is when it runs it seems to run very rich... meaning I can smell fuel very strong in fact outside of the vehicle.
someone told me maybe the fuel temp Sensor might need to be replaced, causing it to dump more fuel then is necessary.

Also have a exhaust Manifold Gasket on the passenger side that needs to be replaced, and the same person suggest that this could cause a vacuum on the system causing it to dump more fuel then necessary! Not sure if this is the Case thought I would Ask some of you Pros, especially the Ones that Specialize in Older Fords!

Thanks for any help in this Regard!

Not an expert, but thinking a leaky injector?
Blocked Air filter can cause engine to run richer.

Replaced Air Filter with a new K&N Filter the other day, so I don't believe that is causing the problem, however a leaky injector could be the problem, need more Expertise on this Subject.

How about it you FORD Pros what's the verdict?

. Remove the K&N Air Filter, if it's an oil impregnated filter, and use a pleated paper filter. Oil from K&N filters often contaminate MAF Sensors and waste a tremendous amount of fuel. This could be the fuel you are smelling. Ford explicitely says not to use oil impregnated air filters. I would follow the procedure below:

. Replace the Engine Coolant Temperature (ECT) Sensor, which affects fuel injector pulse width, if the problem persists. The ECT Sensor is a temperature dependent resistor (thermistor), whose resistance decreases as the engine coolant temperature increases. It provides a richer mixture when cold, leaner mixture when hot. They become corroded, due to not changing the coolant frequently enough, flood the engine, and waste a tremendous amount of fuel.
