OUR ONLINE CHECKOUT is CLOSED and we are NOT accepting any NEW orders at this time.

We are still fulfilling and shipping previously submitted and/or delayed order requests (as product availability allows) UNTIL NOVEMBER 15th 2022.

But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items).

Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. But we continue to endeavor to answer email inquiries as best we can. And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023.

We sincerely appreciate your patience, understanding during this period of restructuring and/or closing. And a huge thank you to all of you whose support and loyalty we have been the beneficiary of over the 23 years that we have worked diligently to support the information and parts needs of the aircooled VW community!

Adjustable Fuel Pressure Regulator, Carbureted Engines, 1.5-8.5psi, 31800.063
Adjustable Fuel Pressure Regulator, Carbureted Engines, 1.5-8.5psi, 31800.063
 
Adjustable Fuel Pressure Regulator, Carbureted Engines, 1.5-8.5psi, 31800.063 is the highest quality regulator we have found. It has 7mm hose barbs. You can use it with Webers and Dellortos (3.5psi), and Solex/Kadrons (2psi), with a variety of input pressures.

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!

5 of 5 Weber fuel pressure regulator November 15, 2019
Reviewer: Colin Jackson from San Anselmo, CA United States  
Went on my 71 bus 1835cc, big valve heads, 110 cam with dual Weber ICT's.  At long red lights idle would start to slow as mixture richened from fuel pressure being to high.  This pressure regulator solved my problem.  set it to 2.5psi and from idle to 80 I have not a single hiccup.  Wish i'd done it sooner... Thank You!
