Well, I thought it was fixed when we put the restrictor on the fuel pump, but damn it, it's not. Please help!!

I used the existing header tank out of my purchased 415C, but replaced the wing tanks and plumbing (all in better or new shape) from my salvaged 415D.

All vents, supply and overflows are clear, but the header tank overflows unless i block the vent on the header tank cap. This cap is from the D, but installed on the C header tank.

Is it possible the vented cap is not suppose to be there. I'm trying to find the old cap to compare them. I'd hate to fly without a vented header tank and find the fuel won't flow to the engine. It would make for a really bad 1st flight!

It's ready to fly, but this issue...

Any and all thoughts are requested!!
