WEBER 40 IT Carburettor Rebuild / Service Kit – PRV V6

Service kit for the WEBER 40 IT carburettor, a distinctive and relatively uncommon member of the WEBER triple-barrel range.

The WEBER 40 IT is unusual in its design, featuring top-cover mounted floats and needle valves. This makes it mechanically different from the more common 40 IDA3C, 40 IF3C and 40 IDL3C carburettors, which use body-mounted floats and needle valves.

As a result, the 40 IT requires specific service components and should not be confused with rebuild kits designed for the IDA3C / IF3C / IDL3C family.

Main applications

The WEBER 40 IT was used on a variety of vehicles powered by PRV V6 engines, including:

• Peugeot 504 V6
• Volvo 260 V6
• Renault Alpine V6
• DeLorean DMC-12 V6
• Talbot Tagora V6

Why rebuild your original WEBER 40 IT?

The WEBER 40 IT remains surprisingly popular with classic-car and performance enthusiasts.

With new replacement carburettors unlikely to be manufactured again, rebuilding an original unit with a genuine WEBER service kit is a straightforward and cost-effective way to restore proper carburettor operation and vehicle performance.

Rather than replacing an increasingly rare original carburettor, servicing the existing unit allows owners to preserve the original equipment while replacing the components subject to wear.

⚠️ Important compatibility information

The WEBER 40 IT has a different design from the WEBER 40 IDA3C, 40 IF3C and 40 IDL3C.

The 40 IT uses floats and needle valves mounted in the top cover, whereas the other models use body-mounted floats and needle valves.

This kit is specifically for the WEBER 40 IT and should not be confused with rebuild kits for the WEBER 40 IDA3C / 40 IF3C / 40 IDL3C.
