What's normal for inline HP fuel pump noise?
Just finished up a ~2200 mile road trip in my recently "completed"
![]() The noise is annoying but I can deal. Just want to make sure I'm not burning up the pump. Has anyone else noticed a lot of variation in the sound of Walbro pumps? Or is this an automatic "something's not right, check it out"? The one other thing that appears to have an effect is ambient air temp. Every time it's been excessively noisy, it's been 90 or above. I changed the first filter just as it cooled off for the night, and then drove around on the coast for the next week. Here at home it's not often super-hot. On the last leg of the drive back, it was hot before AND after I changed the filter, and no difference was apparent in the pump noise. Does this make any sense at all, or is it coincidence? Thanks guys!
