Fuel leak cannot find.

ok got a 94 7.3psd. I've got fuel dripping out the back of the intake galley. I can see fuel on the top of the motor but I cannot see where its coming from. Any typical places to look? I did check the water seperaor drain...its fine.

Fuel leak

By far the most common place on obs psd's is out of the weep hole on the side of the pump. You can see it with a mirror while the engine is running. Other places would be banjo on back of pump, rubber lines from fuel bowl to pump and lines from pump to heads.

I agree with Stroketech, if the fuel pump has been on for alot of miles that would be the first place to look.

ok it is one of the 2" rubber lines that goes from the fuel bowl to pump. looks to be blue and braided/reinforced line. I'm guessing regular fuel line will not cut it. gotta be high pressure stuff right?

Ive noticed that the fuel line today doesnt last as long as it used to,so I would try to find the blue fuel line if possible.Lasts longer.

yes

it is a special fuel line. I have seen people put regular fuel line on with bad results. Its not to expensive for the blue ones from ford. Dont quote me but it should be less the $20 I think.

surprisingly enough I found some 'fuel injection" high pressure hose from autozone. I live out in the country north of austin so my shop choices are limited. it was lined with blue silicone and then an outer layer of rubber then polyester cord then another layer of rubber. $8 for 2 feet. I needed 1 foot of 5/16" adn 1' of 3/8" I replaced all the lines under and around the fuel bowl. I feel fairly confident it will work but I'll keep an eye on it. It was not the standard rubber gas hose I've used on my old carb gas cars...so we'll see. thanks for the head up everyone.
