MF7 high temp fuel code

If you are getting a upside down triangle on the dash and at times the bus shuts down ( busses with MF7 twin turbo ), you find a code for high fuel temp, check the fuel coolant valve that is located on the left side of radiator for a clogged screen and a clogged valve. We have had two busses already with this problem. The only thing we have done to correct the problem is remove valve, remove fittings from valve, and clean the debris out, then reinstall.
