3003 flooded engine.
Update 2. inj. showed up one day early but before replacing it I gave the presser in the tank thing a try.
put 2 psi to the fcc tank and the inj. started leaking.
Venting is a good thing. If you run the vent line like a return line from the fcc to the real fuel tank and the line fills with gas
it will not vent...if your real fuel tank has no vent there can be problems.
The new inj.is a lot different than the old one.
The new one is not leaking. That is the best difference.
Many have had no problems me no so much.

Where did you buy your system from? Almost sounds like you got a system that had been returned from another customer.
