A few weeks back the filter light came on so put a new filter...came on again a couple days ago figured no way is the filter dirty again so I checked the pressure of the electric pump and was barely getting 3psi with the truck off.

Got a new inline earlier today along with an inline filter before the pump to protect it...within 5 minutes the truck wouldn't stay running...new filter before pump was packed with rust as was the one I changed a few weeks ago

Replace the $3 prefilter and spin on...got down the street was full again...replaced again drove to Walmart to get some more made it no issue...came out put new filter in and the new pump crapped out will be returning tomorrow and getting the carrier/facet pump everyone else runs...drove home on the weak pump that I replaced.....

Any suggestion for clearing the rust from the system?
Doesnt matter which tank is selected...

 

Radiator shops can boil them out. If you don't have one anymore, I heard muratic acid works.

 

The carrier pump upgrade solved the floating rust issue...the screen prefilter caught all the bigger stuff no issue....think it got in there from the fuel itself not the tanks....

 

New tanks are cheap.
