Peterbilt 379 fuel tanks not using fuel equally

I've used several products and swear by the brand Penray, at least as far as their "Fuel Prep" product works.
Its cheap too. Like I said before, get ya 3 quarts. One in each tank at your next fill up. Then split the last quart between them on the following fill up.
Depending on how contaminated your system is, you may wanna replace the fuel filters after these two fill ups!

 

Oh and I've heard that with the prevalence of biodiesel and bio blends. You should treat your system (1 quart) every six months, as a maintenance item.
But that's assuming you don't get a bad batch of fuel.

 

Did you fix it?
I've the same problem and I don't know what I have to do, I replaced to many parts and still with the same trouble. Please let me know if you know how to fix it.

 

Can you help me with same problem please

 

At least they’re easier to spot than sandwich bags. One of those can drive you nuts for a long time.
