Bad BAP or FRSP?

Bad BAP or FRPS?

The other day the car through a P0190 fuel pressure sensor malfunction error. Then shortly after that the fuel pressure was all over the place and the car was stumbling to the point I had to unplug the FRPS to get it to drive home.

I ordered a new FRPS and a FRPS disk from KB to help protect the sensor from fuel pressure spikes.. I installed both and at first all seems fine. I stopped to buy gas and when I went to leave the same thing happens again. I unplug the FRPS and it cruises home fine.

When I made it home I plugged the sensor back in and starts acting up. I decide to go to the trunk and check out the KB BAP I have. It was humming really loudly and when I turned it off it started running fine again.

So basically I have a very noisy BAP that's only 3-4 months old and the car is only drivable with either the BAP turned off or the FRPS disconnected?

Any help would be appreciated.

Is it getting hot? My BAP burned under WOT after about a year. I wouldn't reccomend them to anyone anymore. Just get a bigger fuel pump.

Not sure if it's getting hot or not. I didn't touch it. I do know I can hear it now. I wish I would have put dual focus or gt pumps in my cobra setup instead of the bap.
