Carburetor Pre-Heater Hose, 36 Long, 1-3/4 Diameter, Each

EMPI Carburetor Pre-Heater Hose - 36" Long x 1-3/4" Diameter

VW Fitment and Product Overview

This EMPI aluminum carburetor pre-heater hose is a vital component for maintaining optimal engine temperature in air-cooled Volkswagens. With a 1-3/4 inch (approx. 45mm) diameter and a generous 36-inch length, it is designed for VW Type 1 (Beetle/Bug), Type 2 (Bus), Type 3, and various Dune Buggies or Sand Rails. The flexible aluminum construction is corrosion-resistant and rated to withstand temperatures up to 450 degrees Fahrenheit, ensuring durability in the harsh environment of an engine bay.

Pro Tech Tips

Eliminate Carburetor Icing: This hose is not just for show; it plays a critical role in cold-weather drivability. By ducting warm air from the cylinder heads or exhaust manifold into the air cleaner, it prevents moisture from freezing inside the carburetor throat (icing), which can cause stalling and poor idle during humid or chilly conditions.

Custom Trim for Safety: While the 36-inch length provides plenty of reach, you should trim the hose to the specific length needed for your engine configuration. Use heavy-duty shears to cut the aluminum, and ensure the routing is clear of the alternator/generator belt and any sharp edges on the engine tin to prevent accidental damage or entanglement.

Ensure a Vibration-Proof Seal: Aluminum pre-heater hoses can sometimes vibrate loose from the air cleaner snorkel or the engine tin heat riser. To prevent this, use a small hose clamp or a high-temp zip tie at both ends. This maintains a vacuum-tight seal and ensures the warm air reaches the carburetor efficiently without leaking into the engine bay.
