WEBER INLET FITTING for 8mm (5/16″) push on hose
Weber 12mm Inlet Fitting for a regular 5/16″ rubber hose.
All Weber IDA carbs come with a useless banjo fitting we have never figured out how to use (unless you tap it 1/8-pipe and use a “barb” fitting). This will replace the stock inlet fitting with a hose nipple that you can push on and clamp regular fuel hose to. This is the stock fuel hose size for all Mazda RX cars.

The 12mm Stat-O-Seal is strongly recommended for this fitting — it is at: WEBER INLET SEAL, STAT-O-SEAL FOR 12MM

WEBER MANIFOLD for PERIPHERAL PORT 13B 48 or 51IDA RACING BEAT PERIPHERAL PORT HOUSING
Weber Manifold for Peripheral Port 13B 48 or 51IDA
This manifold is designed to fit the Racing Beat Periperal Port 13B Rotor Housings.Works with IDA carbs from 48mm to 52mm bore.
The Racing Beat-designed and manufactured Peripheral Port Intake Manifold mates a Weber 48 IDA or 51 IDA downdraft carburetor, or equivalent throttle body, to the Racing Beat-manufactured 13B peripheral port housings. (This manifold cannot be used on the Mazda Factory Race MFR housings.) The steel tubing manifold is attached to the rotor housings with hoses that are included. A simple support bracket fabricated for your particular application, typically attached from the carburetor-manifold junction to the threaded bosses on top of the rotor housings, will complete the task.

WEBER NUT 8X1.25 WITH 10MM HEX
Weber Nut 8X1.25 With 10mm Hex

These use a 10mm wrench which gives you room to tighten the nut.
Hard to find in “not jet nut” style and in steel. They can come in handy in many other places also.Click Here for a Weber 48IDA Suggested Parts List
