Product details
The JayCee JC-4367-0 is an extended-length float height gauge for Weber, Berg, and EMPI IDA carburetors that mounts on the carb so you can check and adjust the float setting while tuning. The extra length reads higher float settings than a standard gauge. Its billet cap has a breather, so the gauge can stay installed during dyno testing and adjustment. EMPI lists the material as race fuel resistant, and the gaskets and brass mount needed to install it are included.
Setting fuel level on a Weber IDA has traditionally meant partly taking the carb apart, which makes small float changes slow to test. Parts often ordered with it for 48 IDA and EPC 48/51 carbs include EMPI's 3.0 needle and seat that replaces the 2.0 (43-5343-0), the brass float (43-6973-0), and the top gasket (43-5349-0).

Fitment & Compatibility
EMPI lists the gauge for Weber, Berg, and EMPI IDA carburetors. Weber IDF and EMPI HPMX carbs are not on the list, so confirm your carb is an IDA type before ordering.
Common Questions
Does this work on IDF or HPMX carbs?
No. It is specified for Weber, Berg, and EMPI IDA carburetors only.
Can it stay on while I run the engine?
Yes, for testing. The breather in the billet cap is what lets it stay installed for dyno runs and adjustment.
PMB Performance can help match float parts to your IDA setup.
