Hello

Hello Everyone,
I'm new to the site. I own a 2003 F-150 crew cab truck, with 368K miles, and my fathers 1999 F-350 7.3L diesel with 100K miles. Main reason for joining is researching a fuel leak on the diesel, passenger side. Looks like it might be fuel drain o rings, and bowl orings. Ordering parts from diesel orings.com, will post my results!
take care,
Edgar

I recently went through this on my '99 7.3 SD. I thought the same thing. IN MY CASE it was a fuel line. There is a steel fuel return line running from from the fuel filter area to the back of the passenger side cylinder head. It passes through a steel hose clamp (that holds it to the head) and the rubber was all gone. Steel on steel. That's where my leak was. Supposed to be common. Sorry I didn't get photos.

I had exact same Fuel leak at clamp, passenger side. 2000 F250SD 4x4, 7.3PS. R&Red tube from fuel filter to rear of engine block. I left clamp off. Local Ford Dealer had part in stock. Seems like a common problem on Diesels.

Replacement fuel tube from fuel filter to passenger side rear of motor. 2000 F250SD 4x4, 7.3PS. My 1st post, ALL SHARED HOW-TO INFO IS APPRECIATED. I have learned so much here!
