changed fuel filter,and truck runs wierd.I think it might be getting air in fuel line.When I prime it,it becomes hard to push then in about five minutes I can prime it more,is this a sign of a leak?

When you prime it are you cracking the bleeder screw? What do you mean it runs wierd? What is it doing?

 

[brad h]

Its got more drone to exhaust/and lots of vibration in pedal,just doesn't run the same,like loss of power ,and the bleeder is closed

Not likely related. If you had air in the system it wouldn't run, it shouldn't cause it to run rough.

It just seems like before the primer always stayed hard to push/also any suggestions on fuel additive.Thanks

FPPF seems to be a popular choice. Primerose is good as well. I personally run standyne because I have a hard time finding anything else around here.
