As promised here is a run with fuel pressure logged

This is with the FB340 pump. Boost 17-18psi

 

What fpr u running? Stock? Maybe that's the problem. Fuel pressure dropped something fierce up top .

18 psi shouldnt be a problem for a single pump. Clamps or lines possibly inflating. Maybe voltage dropping at pump in boost?

 

What fpr u running? Stock or aftermarket? Maybe that's the problem and that part is broken . Maybe clog or kink on the line?

Its an aem regulator. Ive tested it with regulated shop air and it held over 90 psi fuel pressure no problem. The lines are all factory. As far as I can tell they are fine.

For the hell of it I flow tested my injectors tonight...i know bad flowing injectors would not cause a pressure drop, but it was worth testing out.

Here were the results...pretty good static flow variance. Better than most aftermarket injectors I have tested.

 

From the dead.

I am installing a Walbro 400 tonight. Anyone else have any issues/insights to this install? Looks like all you have to do is trim a few inches from the bottom of the hanger?

 

That was the biggest pain in the ass. Ever.

 

Was it really or was that a sarcastic expression? Explain.

I wonder if the pain is worth using this pump.
