94 7.4 turbo IDI. new to me truck. Been running good for a few weeks, fuel light came on so i changed the filter, light went out for a few days then came back. It had a new mechanical fuel pump but I went ahead and bought a facet electric fuel pump. Went to drive it today and same thing as before 3 gear hard acceleration and fuel filter light comes on. Where should I go looking for issues as I understand the light only come on if the ip goes into a vacuum and my feed pressure to the filter should be 9-11psi with the electric pump.
