Does anyone know how much fuel should come out all three lines from the fuel pump when pulling over the sled?
Is it small little bubbles or a good squirt each time.
I have a Viper that is not getting enough, the manual does not really say how much you should see.
Looking for any opinions on trouble
 
Fuel pumps seldom fail in my experience.
What I have seen on them is the little crossover tube on the top of the pump can get hard and brittle, then get a crack in it.
Not sure if that affects fuel flow or not, but the largest line coming out of the fuel pump runs to the crankcase. If that line has a leak, you will get poor flow. When sled is running, and all is right, you can hardly tell the fuel pump is doing much. So, you will not be seeing any squirting or such.
 
Thank you much for the reply. I am going to pull inlet line and filter from the tank first for inspection.
Go from there after that.
