Been through 6 in total.
First failure was the primary pump got lazy. The secondary covered it when it come online. Picked it up by a fuel pressure gauge and AFR gauge.
Replaced both...
Second set,same thing.
Third set, can't really remember... But enough to crack it and throw it all in the bin.
044's DO NOT last under E85 conditions. If you don't have gauges and running them, you're asking for trouble.
