The 1974 Beetle fuel filter hosts an in-line fuel filter. Some fuel filters fit in the engine compartment near the master cylinder. The fuel filter for the 1974 Beetle, however, fits beneath the Beetle, connected to the inlet hose from the fuel pump and the outlet hose to the engine. The fuel hoses are 6 mm or 8 mm in diameter for the 1974 Beetle, so you should buy a filter that fits those specs.
Tools Used: Car jack, Tire iron, Jack stand, Hose clamps, Rag, Screwdriver, Replacement fuel filter, Penetrative lubricant
Connect a Fuel Filter
Engage the emergency brake. Raise the 1974 Beetle with your jack and tire iron. Position a jack stand under the 1974 Beetle on the driver's side. Lower the Beetle onto the jack stand.
Set the hose clamps onto the hoses attached to the fuel filter. The hose clamps prevent gasoline in the hoses from spraying on you. Place a rag below the fuel filter to collect any gasoline that drips out as you work.
Loosen the screw on the fuel hose rings to pull the rings away from the fuel filter. Wiggle the fuel hoses off of the filter. Press in on the tab on the strap holding the fuel filter against the Beetle to disengage the strap from the bracket it is locked into. Remove the fuel filter.
Install the replacement fuel filter. Wrap the strap around the fuel filter. Engage the strap in the slot on the mounting bracket. Connect the hoses to the filter. Secure them onto the filter with the hose rings. Remove the clamps.
Turn the Beetle on a few times in quick succession. This action activates the fuel pump, filling the filter with fuel. Look below the Beetle for any leaks near the filter. Lower the Beetle by removing the jack stand and jack.
