It is right on top next to a hose that also runs into the top of that crossover tube.looks like maybe 1/8th inch diameter chrome pin w/ a black rubber cap and hose clamp. It is squirting from there.didnt know if i can replace that piece

Are we talking 4.6 or 5.4? It would help if you filled you signature with your year, eng, upgrades and what not.
