Depends on what number fuel grade you put in and how cold it is also. I get more bubbles in both trucks with Davco 382’s when it is cold (like I am sitting in -10 weather this morning) and I use Number 2 during the winter unless it gets -15 -25 range then I get nervous and throw in some Number 1.

Like Waterloo said maybe you have pinch O-rings also? Is the truck running rough? I say if it is not then not to worry about it.
