Good morning,

I would remove the fuel rail and flush it out of all that stuff. The injectors may have been damaged from this as well.

Remove the tank and have it flushed out and I would replace the fuel pump as well.

Blow out the lines to the front as well.

Lot of work to do to return this to normal operation.

REMOVAL
1. To reduce the internal pressure of the fuel main pipes and hose, first start the engine and then disconnect the electrical fuel pump connector located near the fuel tank.

CAUTION: Be sure to reduce the fuel pressure before disconnecting the fuel main pipe and hose, otherwise fuel will spill out.

2. Disconnect the battery cable from the negative terminal of the battery.
3. Remove the fuel tank cap.

INSPECTION
1. Check the hoses and the pipes for cracks or damage.
2. Check the fuel tank cap for proper operation.
3. Check the fuel tank for deformation, corrosion or cracking.
4. Check the fuel tank inside for dirt or contamination.
5. Check the in-tank fuel filter for damage or restriction.
6. Test the two-way valve for proper operation.
7. Using a vacuum hand pump, check the operation of the two-way valve.
