Fuel boiling in new Edelbrock 1406

[miketyler]

I just installed the 1406 yesterday and got the idle set. I took it out around the block and died when I slowed to make a corner. Would not start and when I pulled the air cleaner I could see fuel stanidn on the main throttle plates and was boiling. Also noticed the tell-tale leak around the shaft as well.

I will need to get a fuel pressure regulator (not a c-clamp) on it to be sure it isnt over pressured and pushing past the needle/seat valve. If the fuel is boiling I will still have a problem once I fix the flooding issue. I am thinking I may need to try and insulate this thing. What do you use? The heavy insulated gasket? Or maybe the thick phenolic spacer? Engine is a bone stock 340

I have a 1/2" thick phenolic spacer on mine. It's amazing how hot the intake manifold can be, yet my fuel bowls are cool.  Vapor lock $ucks!!   

I'm surprised this happened to you just driving around the block.    I know you have had overheating issues before. What does your temp. gauge tell you?

I had been running it getting it the idle set so it was nice and warmed up when I pulled out of the driveway. Yesterday was crazy hot here at 105, and I had the AC going. Temp gauge was creeping up on 210. Seeing the fuel puddling on the floor of the primaries is more than likely a result of my high pressure but the boiling is going to need to be addressed next.

From all I've read phenolic, while old school, is most the effective low tech approach
Consider those crossover block offs too.

One common thing is to take off the air horn and set float drop.  They are ALWAYS too low, but checking pressure is good too.  They don't like more than 6 psi.

Definately pull your Intake and block off the heat. It's worth 10-15hp.

Get a Holley...gave up my Edelbrocks long ago.

I bought a 1" phenolic spacer and it appears to be ok now. I had an Avenger previous and couldnt get tuned correctly. I will be listing it and a LD4B 318 intake for sale soon

I agree with Wade...tons of heat from the crossover. Did the block...it worked for me.

Check the float levels too. It should not stall in corners. It's normal to see some fuel wet on the throttle plates right after you shut it off. So it doesnt mena its bioling or flooding. If it was fuel pressure, you'd know it by more than wet throttle plates. Floats can get out of whack in shipping without anyone knowing. So it's the first place I'd start looking.

I think I am good now. I put the phenolic spacer on to remedy the boiling. I put the regulator on and adjusted up to 5psi and all seems ok. Drives good, steady idle and doent die taking a corner.

I haven't looked down the throat to see if there is any fuel standing on the primary plates but I wasnt getting the tell-tale leak from the shaft so I'll bet its probably good to go as well.
