Hi Guys
Running an Old walbro part# is gss-342 and Ti changed it to Efp-058.
Car starts, idles and runs great.
Pump is quiet when started.
After driving for around 10-15 min the pump starts to get very noisey and I loose power. Fuel pressure drops to 15 psi
I stop the car and wait a couple minutes and start again and drive off everything is normal until about 10 min down the road and same issue again.
Car never stops just looses power after a while due to low fuel pressure and fuel pump screaming.
Please help. The fuel pump is brand new and tank half full.
