Ok here is the deal, I just bought a dune buggy with a 2.9 liter ford V6. It is idling well, runs decent, but when I get into the throttle it will just randomly fall on its face like it is losing fuel. I know there are many things to check to fix this problem, but I would like to start with making sure this aftermarket fuel system is hooked up correctly, because I am doubting it is routed correctly.
My fuel system is currently set up as follows:
Fuel tank mounted higher than everything, so gravity will technically prime everything.
inline clear fuel filter (new) to a fuel pump ( wouldn't be surprised if it is the stock ranger high pressure pump), then an aftermarket pressure regulator which reads 40psi at idle.
The aftermarket regulator is then ran directly to the fuel rail.
Then I believe the stock pressure regulator (mounted to the fuel rail) runs back to the fuel tank. And there is a constant re circulation of fuel into the tank from that stock pressure regulator.
Does anyone have a description of how the fuel lines are ran in this engine? I don't see why I need the aux pressure regulator. Unless the stock regulator needs something that I dont have due to the engine swap (electric connection, vacuum, but I should have the same vacuum even with the swap)
