Re: Evo X upgrades

Shawn, I had considered that and plan to re-test by visiting O'Reillys today. I had been trying it every twenty minutes or so.

Right now my assumption is that the hanger needs to be pulled and modified so it doesn't have slits in it that allow the fuel to get away from the pumps. My theory is that the in-tank pumps were dry despite having 3/4 of a tank, due to the grade of the parking spot. The obvious problem is that you do have to park on hills once in a while, in real life.

I did discover this morning that the Bosch is over-running the stock fpr. It's around 57psi at idle, which is way too much.

Two possible solutions:

1) Rewire pumps so that the Bosch is powered from the car's relay and the in-tank is always on using the add-on relay. I know that MDR suggests this as an optional wiring approach in their surge tank instructions. I'm not sure if it'd be enough to make the stock fpr happy but it'd lighten the load.

2) Install the afpr. I appear to have everything that I need other than a bracket to mount it to the front of the motor. I can either McGuyver something or wait and see if Full Blown can fabricate something decent next week.

Right now I'm leaning toward rewiring it tomorrow...that way I can just go bonkers with wiring, both that and the gauges.
