Edelbrock 9266 Heat Insulator Gasket

I bought a 1979 F-150 in November 2022 and I have been restoring it this summer. The old carb needed to be rebuilt after years of sitting but I ended up swapping to a new carb instead. Once we started getting air temps over 80* I noticed rough idle, hard to restart when warm and off-idle hesitation. The carb was too hot to touch when it started running like this. Did some internet sluething and due to low fuel pressures that carbs use and modern fuel blends, the fuel likes to vaporize at lower temps than it has in years past (or so the interwebs says) since most cars run modern fuel injection with much higher pressures these days this is a non-issue. So I need to keep temps down to keep the fuel from boiling in the carb...which brings me to this nifty Edeldbrock insulating gasket. I ordered this with the Edelbrock 8725 carb spacer and ARP 2002402 carb studs long enough for spacer, gasket and carb base. I've not had the vapor lock issues since and the carb no longer gets too hot to touch, you can touch with bare hands as much as you want at full operating temp. No longer is it difficult to start when it is at operating temp. I love when it is something basic that you can do to fix the problem.

My truck has a dual plane intake and a spread bore carb. Never ran right. Upon inspection I could see that the wrong base gasket had been used. It runs so much better with the correct gasket, which is thick and works as an insulator to prevent carb from boiling fuel.

Nice Gasket but did not use, ordered the wrong one. Returned

I guess the manifold should have been made a little high. Anyway that 3/8” of a inch raising the carb made the difference.👍

The studs that came in the pack, no way are long enough. I had extended studs on already and they still were not long enough. I am running Edelbrock manifold, Edelbrock Carb Spacer, and Edelbrock 600 CFM Carb on my 289. I assume many are running a similar setup. Had to order a set of 3.5" studsOther than that, was the easiest thing to instal. Feels quality and fingers crossed my vapor lock is gone.

great gasket

Why edelbrock don't include this with their carbs when you buy it? I've had hard restarting issues after the motor got hot on my edelbrock 1406 600cfm. The carb would get hot and boil the fuel out. I read about this heat insulator and ordered it. Install was simple. Kit came with longer studs. Used the old gasket between the insulator and carb. No leaks, no issues with hood hitting the aircleaner wingnut. Best of all, after getting the motor hot, I turned off the motor waited 5 min. It restarted with no prob. Problem solved. 👍👍👍

Fixed my heat soak issue. I didn't even have to remove the linkage or replace the studs. I was literally done in five minutes since the gasket on the carb was in good shape I just left it in place. Runs perfect. Before this I drove the car ten minutes (four miles from home to the gas station) and had to let it sit for hours before I could restart it. Aluminum manifolds are just to damned good at transferring heat. I wasted a whole can of ether trying to cool it off evaporation to no avail.

Good product

I wish I had this since day one. Solved my heat soak/vapor lock problems. I can now drive my old boogie van (600 edelbrock carb) for a long drive and then touch the carb afterwards and it’s only warm while the intake, engine and headers are hot as hell.

It’s made for the intake I am using. I would recommend using this product.

Good quality. Does the job. Came with the longer studs

Worked for me .
