I have a 93 f350 diesel 7.3 idi. I have noticed a fuel leak that is coming from what looks like the front tank return line. This line could also be a pressure relief line should the tank be overfilled or pressure builds from heat. The line terminates with what looks like a plug that can allow the relief of pressure. Can someone help me get the right name of the part and then where can I find a new one? Thanks

 

.One of the things you can do is;

Go to a dealership parts dept and explain what you are looking for.

They have all the diagrams and part numbers for each part. There you would have the opportunity to pick out what you are looking for.

Since there are many parts with this system , it would be pretty difficult to get this done on line.
