I have a question for Walbro kit owners.

When you start you truck does it take a while for it to build pressure after the motor is running?

I have noticed mine will build pressure when you cycle the pump, say about 5 lbs., and when the motor starts it will drop the pressure and slowly rebuild back to 16 lbs.

Idles at 16 lbs.
Can't pull it below 14.

Mine is the 392

Is this common? right? doing damage?

 

IMO Sounds Normal It takes a bit to build Head

OK, I am a goof ball, forgot to update.

Got it fixed, my needle valve for the pressure sender was closed too far, opened it up a bit and now I have instant response.

Thanks DM.

 

Good To Hear !

 

 

Now that's not very nice right there!!!!!!!!!!!
