Have a 440 with OE HP intake manifold and Edelbrock 1411, 750 CFM carb. Having occasional issue that appears to be vapor lock. I've seen the "Cool Carb" solution at Carlisle and other shows. However, I can't reach them by phone or email. Does anyone know if he's still in business? As an alternative, I was thinking of purchasing this... https://www.summitracing.com/parts/edl-9266 . Anyone have any experience with this part and if it really helps?
(I've heard that installing a secondary, electric fuel pump to switch on only when vapor lock occurs might also be a good solution. But I figured that I'll try the simpler, no-moving-parts solution first.)
TIA,
Mike
 
Mike, Check and see if your fuel line routing is touching your engine/manifold in any place. It's best to have as much space around the fuel line and/or insulate the line. Also, Dave @ Woodruff is an excellent source to question as he had many solutions to problems I had. I don't think he's that far away from you in Glenmore, Oh. just above E.Liverpool
 
Any vehicle vapor lock issues that I have had in the past can be solved by fuel vapor seperator type fuel filter with a return (i.e. 440 & Hemi cars had them), or a phenolic type carb spacer/insulator. If hood clearance allows for one.
 
Thanks to you both for the suggestions. I was totally unaware of the "phenolic" spacer. The one from Edelbrock is made of nitrile rubber composite. I'll research more, but I'm wondering if phenolic material is inch-for-inch a better insulator than nitrile rubber composite. And Glenmore, OH is only a tad more than an hour from me.

Phenolic is better
 
The Edelbrock spacers "work" if hood clearance allows for it. Thinnest you can get from Edelbrock is in the rubber insulator at about 1/3". Canton makes a 1/4" wood fibre spacer & there is a Holley 1/4" spacer that you can still find on eBay that also "works" but had to massage the bore holes for a AVS2 800.

If the fuel is getting hot in the lines however, you'll continue to fight it.

In addition to the Holley brand spacer, I added a 3' "fire hose" sock for the steel fuel line that comes up into the engine compartment to shield heat from the headers.

I also run PTFE lines from the steel line to the pump & pump to carb. The nylon outer of the PTFE keeps the heat at bay as well.

Oh and as for Cool Carb, yeah I think they are done. I emailed them for more info, never heard back. I am not sure that I could have put such a ugly solution on my engine though.

Block off the heat risers in the intake, run a return line and a vapor separator, or 3 port filter, as well as the spacer/heat shield.
 
Don67... I'll add a DEI Fuel Line shield to my shopping list. Not expensive and could well help the cause given my 3/8" metal fuel line.
4speed68... Good ideas as well.
 
I am a fan of 1/4" phenolic spacers but wood ones are actually better. I make them when I need to. Easy work on my mill. Even better o ring your spacer - no more gaskets! This one was phenolic and is thick because its profiled and intended to be a spacer not just a heat insulator. I also added locators - this is a dominator.

I have fixed carb heat problems on street cars with 1/4" phenolic spacers before.

I use that edelbrock gasket, now I do have aluminum heads and intake, but I’ve never had vapor lock issues and it’s gets hotter here then up where you are. Give it a shot and hopefully it helps :thumbsup:
 
Just a little tidbit of information with regards to vapor lock...

I tried solving a problem for years on my 383 with stock manifolds was having. I placed a clear fuel filter so I could see the percolation. I tried all kinds of possible solutions including carb spacers and running a vapor line with the different fuel filter. Didn't work.

I tracked it down to the heat riser shaft on the passenger side exhaust manifold. There was a hole as I recall for some purpose near the shaft. I could actually feel the stream of heat coming out next to the fuel line. This made no exhaust noise.

You could use something to hold a piece of paper --or whatever-- and send it down there to see if it flaps around as the engine runs. I could actually just fit my hand down there and feel the stream of heat.

I brazed it shut. Someone else might choose a different route but it worked. It may not be your problem but it's something to throw out there in case others read this post...
 
The best route is non ethenol fuel if available. No more problems. I have several cars and since switching to it everything is great.
