fuel module

[Don.F.Broadus at ucm.com]

Thanks for the info, I should be ok with out the module then. 
Does anyone know what this ECM came off of 1228322 ALCP calpak
It was given to me, and searching the list didn't come up with anything.

                                                                      Thanks
again     Don

	Basic function of fuel module (AKA hot fuel handling module) is to
keep
	fuel flowing for up to twenty seconds after engine is shut off to
	prevent excessive boiling in the fuel lines.  There's a good chance
that
	you will never see problems without the module, but maybe during the
	right conditions you'll have longer crank times.  I think there may
be
	long term benefits to including the module.
