AFA the fuel, how did you set up the fuel system?  Do you have the pumps (you have at least
two, yes?) set up below the bottom of the fuel cell so as it's not 'sucking air'?  Which fuel
filter are you using? After you started having problems, did you swap in another fuel filter
to make sure there wasn't crap in the fuel cell clogging up the system?


Some discussion on fuel cell/system set up here:

Also, from a SCCA G2 ProRallier (chief mechanic & driver) on setting up a
fuel system for fuel injection:

 Re: Fuel pumps & fuel cells

Just some starter info.  My carb'd G2 SAAB 99 is set-up w/ a Fuel Safe fuel
cell, two in-line Holley pumps, & a hi-po aftermarket filter.
