You need to check your fuel pressure.
You need to drill and tap the banjo bolt on the injector pump inlet. Use 1/8" npt tap and get the appropriate fittings. You will also need a needle valve to dampen the pressure spikes from the injector pump. Youre setup should look like this: - Last edited by Dr. Evil; 11-03-2009 at 12:23 AM.. |

This can sometimes be a sign that its not putting out the correct pressure but in order to be 100% sure you must check the fuel pressure with a gauge.
