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 regulator comes with a mounting bracket and hardware, the barbs are perfect for 5mm and 7mm hose used on vintage VWs.
The heavy wall 2" OD x 2" long glass enclosure makes it easy to see what is in your fuel, including water! Easy to clean and engineered to last, you will want one for all your carbureted vehicles.
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!
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.
