Aeromotive Stealth 340 Low Pressure
Installed this pump about 4 months ago, it was problem free until recently. I was getting lean codes and couldn't find any vacuum leaks so I put a pressure gauge to the fuel rail and two different days only saw 28 PSI.
My first assumption is the pump is slowly dying, but a reputable performance shop told me something has probably come loose/ broken inside the tank.
What do you guys think is more likely to be the problem, just wondering if I should even bother dropping the tank without another pump ready to go. Trying to minimize downtime, but my experience with fuel pumps is minimal.
This is on a 2006 Trailblazer SS with a TVS1900 (just 6 PSI). Also what is the feedback on the 340? Good? Bad? Should I be looking at going back in with something else? Maybe the Walbro 400?
Thanks in advance.

Was it 28 psi at idle or under hard throttle or what? I just had a huge issue with all this, and realized my pump wasn't big enough for one, and it was also sitting in the bucket wrong too

I'd give the wiring a look. Including the relay. Aeromotive suggests a 40amp relay and 10ga wire. I just installed mine with all that stuff and at idle its pulling 16 amps. Its a beastly little pump and more than enough for your setup.
I had a supra pump in before are it fried 14 ga wire. Gave me low pressure for a week then fully died.
