So I’m in the process of getting my fuel system installed and working properly as I didn’t go with the original cowl tank route.

Instead I have a RCI 15-gallon fuel cell, plumed with Fragola 6an lines and fittings to a K&N/Facet in-line pump 1.5-4 psi going into a pressure regulator hooked up to the fuel bowl for a nice concealed look.

Here’s the issue: with the regulator screw loosened counter clockwise (lowest psi setting 1-1.5) the pump still sends way too much fuel to the bowl, and eventually overflows. Yikes - the engine doesn’t even have the ability to keep up with the amount of fuel heading downstream.

I ordered a new Holley 1-4 psi regulator as I’m guessing the one I have from summit is is not regulating as designed? Gauge needle doesn’t even move… What else am I missing here Model A gurus? Here are some pictures to help show what I’ve done so far. Lines haven’t been fully attached to the frame rails yet as I’m still “in progress” but this first fire up today was a speed bump, as I had to essentially drain everything and sit there stumped trying to figure out why my system was sending so much fuel to the bowl…. The carb wasn’t even sucking it down the hard line either! Which is even more odd. It ran for a little bit on fuel I assume got pressurized and sent into the carb bowl, but it eventually sputtered and died, even know the glass sediment bowl was full of fuel? I did have the red cap off the tank (vent) fitting as well. Picture was taken before I ran it this afternoon.

Thanks to anyone who’s got some clues for me. I searched, read all the similar topics and couldn’t figure out what I did wrong…
