No fuel after start up
Put a vacuum gauge on the pump entrance and turn the motor. So many of the replacement pumps are not properly bent to contact the eccentric.
On all later mopars they had a filter with a return on them to accommodate the ethanol fuels . 87 was the last year then they started injecting them .
My car would vapor lock constantly and it had an electric pump at the tank. The fuel would vaporize at the engine and cause the float not to work. After putting this return on I was able to get the rich lean gauges correct. The problem was more noticeable on restart on my car. The fuel would flow constantly and never boil. I have installed the later filter on early factory pumped cars with a return to the tank. It works great.
I have noticed this only occurs with pump gas . C14 leaded was better without a return.
