Re: Fuel is boiling
I have put on Felpro intake gaskets that have the exhaust ports blocked off. I have added a Holley heat shield as well as a phenolic spacer. I reduced the fuel pressure down to 4 psi. I made sure the float bowl wasn't loading up with fuel.
Fuel is still boiling!! I am already running a Holley electric fuel pump with regulator and return line.
Any other suggestions?? I'm at a total loss.
OK, I realized what was happening. After the engine and fuel pump were shut off, residual fuel pressure(which I assume was coming from the tank) continued to drip fuel down into the manifold. #8 cylinder was full and I couldn't even turn it over.
Removed fuel cap, pressure released. My "vented cap" will suck air in, but it doesn't seem to let it out. I found this out by blowing on the inside center of the cap and then sucking on it. Air seemed to flow freely in, but it was very difficult to get any to go out. I drilled a damn hole in it. I'll let you know if that works.
