Once you use these you will never EVER go back to the Brass Nuts (that strip and round off), or the barely better 12mm ones out there.

These are a LOT smaller than 11mm on the Head, and the flange keeps the header far enough away from the nut to allow your socket or wrench head enough room to get on and off!

We use these all over because they are so useful. The obvious application is header nuts, when you have a larger than stock header. These even work on exhausts as big as 2 1/4"!!!!! The not so obvious application are to hold down your intake manifold(s)! Now you have a ton of room to use a FAST Ratchet with a long extension above the carb top! You can take a dual carb system off in under a minute after a little practice! Imagine, no more bloody knuckles after an hour of fighting your car!!!!

You can use one in one filter, or one in each filter and T the hoses to even the distribution.

If you have OPEN preheat flanges on your exhaust system, you can use these to easily and quickly close them off. The most common situation is where you had a stock carburetor, and now have dual carbs! Duals don't need preheat, but the flanges are open! Voila'

Comes with 2 block off flanges and gaskets.

Many owners buy these when fabricating their deluxe pre-heat system on their aftermarket headers. It's cheaper and easier to buy these and drill a hole in the center for their pre-heat flanges than trying to fabricate from scratch! If you do this we recommend 5/8" seamless mild steel tubing.

Hose clamps are not even needed, because the cloth woven on the hose surface acts like a "Chinese finger trap", and keeps the hose tight on the fitting. Some owners choose to err on the side of caution and use clamps also.

Price is for a meter of hose.

This fits flat on the barrel (mouth) of the carburetor. It requires an extension or adapter for Kadrons due to the centrally located air filter mounting stud.

This book is KILLER on understanding the operation of the Weber carburetor!

This is the parts and labor to have your intake manifold(s) PROPERLY modified with a port put in them so you can just slip your power brake hose and check valve on, when installing your carburetor(s).

This fits inside the barrel (mouth) of the carburetor. It requires an adapter for non-round "Internal" carb throats such as ICTs and DCNFs. It also requires an adapter for Kadrons due to the centrally located air filter mounting stud.

This is the less expensive ECONO model (made in China or Taiwan), NO GUARANTEE OR WARRANTY ON IT!

This regulator comes with a mounting bracket and hardware, but does NOT have fuel line barbs, which much be purchased separately depending on the size of fuel hose you are using. If you have a single carb, you can simply plug one outlet port on the regulator and run it as just a regulator rather than a Tee also.

Note that proper fuel pressure is critical for proper carburetor operation. Weber IDF, IDA, ICT, DFEV/DFAV, and DCNFs work best with 3-3.5psi, so this regulator works for all of them, even if you switch carburetors sometime in the future!

This is an EXCELLENT regulator to use with the stock fuel pump. Normal methods of dropping fuel pressure with the stock fuel pump are to stack gaskets between the pump and pump spacer, and this does work but it also reduces fuel volume. Using this regulator will keep full volume but wlll drop pressure, which is more desirable.

This fits inside the barrel (mouth) of the carburetor. It requires an adapter for non-round "Internal" carb throats such as ICTs and DCNFs. It also requires an adapter for Kadrons due to the centerally located air filter mounting stud.

This Sync Model is ideal for all velocity stack and carb throats of 1 5/8 to 2 1/8" (40 to 55mm Diameter).

This fits inside the barrel (mouth) of the carburetor, fitting airhorns from 2" (51mm) to 2 5/8" (67mm) in diameter. It requires an adapter to use on the smaller Weber IDF and Dellorto DRLA carburetors.

Fuel Pressure Regulator, Basic, Carbureted Engines, 1.5-5psi is a low pressure fuel pressure regulator that works with most fuels except methanol. Fuel pressure is pre-set to 3.5psi, but it can be set to any fuel pressure between 1.5psi and 5psi. THIS ONE ACTUALLY WORKS, unlike the Purolator, Mr. Gasket, and EMPI Units!

This regulator comes with a mounting bracket and hardware, but does NOT have fuel line barbs, which much be purchased separately depending on the size of fuel hose you are using. This regulator is threaded to 1/8" NPT on both inlet and outlet, and does NOT come with fittings! Buy the fittings you need to match the sizes of your fuel hoses.

Note that proper fuel pressure is critical for proper carburetor operation. Holley regulators are "OK" but don't go below 3psi, and stock carburetors (Solex, Bocar, Brosol, and Kadron) all run best with 1.5-2psi fuel pressure. Weber IDF, IDA, ICT, DFEV/DFAV, and DCNFs work best with 3-3.5psi, so this regulator works for all of them, even if you switch carburetors sometime in the future!

Fuel Pressure Regulator AND Filter, Combination Unit, Carbureted Engines, 1.5-5psi is a low pressure regulator which works with most fuels except methanol. Output is pre-set to 3.5psi, but can adjusted with the turn of a screw to any pressure between 1.5-5psi. This unit also features a 25 micron stainless steel filter element, which catches sand, rust, dirt, and even water! THIS ONE ACTUALLY WORKS, unlike the Purolator, Mr. Gasket, and EMPI Units!

This regulator comes with a mounting bracket and hardware, the barbs are perfect for 5mm and 7mm hose used on vintage VWs.

This is the finest fuel pressure regulator we have found so far; IT ACTUALLY WORKS!

This regulator comes with a mounting bracket and hardware, and has built in 7mm barbs for the fuel hose inlet and outlet. Locknut and adjusting screw, and full instructions.

Note that proper fuel pressure is critical for proper carburetor operation. Holley regulators are "OK" but don't go below 3psi, and stock carburetors (Solex, Bocar, Brosol, and Kadron) all run best with 1.5-2psi fuel pressure. Weber IDF, IDA, ICT, DFEV/DFAV, and DCNFs work best with 3-3.5psi, so this regulator works for all of them, even if you switch carburetors sometime in the future!
