What is the ideal charge pressure on the injection pump? I got fittings and line to make an air vent at injection pump and now i just need to select a check valve with the correct back pressure. most are 0.5 to 1psi cracking pressure but i can get any back pressure check valve or use a holley regulator. The whole purpose of this setup is to lengthen the injection pump life by making sure no air gets to it, and is always supplied with clean 5 micron filtered fuel.
