Hey listers. We are in sunny Baja MX and thought we would toss this out for discussion. 
Some time ago we replaced the fuel tank. At that time we moved the filter to post-pump location. All was great and quiet.  About a month ago we replaced the seals on the expansion tanks. Now the fuel pump is making quite a bit of noise. 
Thoughts or suggestions are welcome!
