if you havn't checked in the fuel filters for a good while,
that would be a good idea.
empty each one out backwards onto a clean dish ..
and examime what is  in them.
I find dirt particles, rust particles, shiny tiny metal bits, and water
sometimes.
blow through each one to see if it's restricted very much.
if very restricted, replace.

did you do the fuel quantity delivery test yet ?
