I just swapped in B16a into an EF. When I turn the ignition I could see fuel leaking out of the fuel rail / hose feed. I put new gasket(muffler) and 12mm washer. Tomorrow, I'm going to swap fuel line feed off my buddy's CRX to see if it does the same. Please help!

 

did you put both washer on both side of the feed line?

 

I got it figured out. There was an extra 12mm washer behind the 1st one. It gave it enough space to leak fuel. Thanks bro!

Engine fired up nicely
