Hi,
Is that a direct bolt up on the tank?
Hi,
How did you check for header leaks?Got started prepping for the install of my Holley Snipper. Started with checking the headers for leaks. Found a small one on each side so I pulled the hearers loose and have order new gaskets. I hate my Hooker long tube headers but will have to live with them for now. I also got the old fuel line off and am getting ready to run both supply and return. I also am ready to pull the fuel tank so I can swap out fuel pumps.
I know some guys won't agree with doing this but I use a small shop vac to pressurize the exhaust. I hook the hose to the exhaust side of the shop vac and then put the hose in the cars exhaust. I loosely plug the exhaust with a couple of rags.How did you check for header leaks?
Nice trick. The only drawback I can see is the possibility of blowing some chunks of carbon or lose stuff back into the cylinder.I know some guys won't agree with doing this but I use a small shop vac to pressurize the exhaust.

I then take a small spray bottle and mix a little dish soap with water. Spray around the headers and then turn the vac on. Wala! - bubbles!
Before doing this make sure you clean the vac and hose out good so you don't blow anything into the exhaust and possibly the cylinders. I also soak everything down first before turning the vac on.
I use a small 1 gallon vac that works great for doing this.
Yeah unfortunately that's the chance you take. That's also the reason I use the small shop vac, it doesn't blow as hard as a 5 gallon one does. The idea is to build pressure with low velocity. I've done this about a dozen times now over the years and haven't had any issues so far - knock on wood. I start the car and rev the engine up some to blow anything out. I then let it cool down to where I can touch the exhaust before I do it.Nice trick.

Thanks. I am rather fond of her as well!Man!! That's a great looking car Chris!!
She's pretty happy in amongst her stable mates. I've had a question or two about the other cars. I'll post up pic(s) in the "Glamor Shots" section later today or tomorrow.That looks like a nice storage location.
