Unhook rubber line at lift pump, remove tank caps and apply compressed air (not more than 90 PSI
) and listen for gurgling... my TSV (tank selector valve
) is clogged enough to where if I switch to the other tank, engine loses rpms and dies...
It's so clogged with asphaltines (small black particles that look like showerhead pieces but are not-whole 'nother subject
) that the TSV is jammed and I plan to take it apart and clean it when I install 38 gallon tank in.
The Ford whiz kids thought it was cool to locate the TSV right in the space between front tank and frame rail and nobody can get to it without dropping that tank with the skid plate.
I have a Facet pump with a line filter right before it and have to change it every so often because it is getting clogged with tiny hard black pieces of asphaltine. When I change the line filter (way cheaper than changing the canister filter on top
) I have to blow back and clear the line so the new line filter (see through
) doesn't get clogged right away.
So anyway, try blowing the lines back to the tank, this won't work on the newer models with the pump in tank setup...
