CarBole Clear-Glass Inline Fuel Filter 3/8" Inlet × 5/16" Outlet — 200-Mesh Nylon, Single Pack

The CarBole 9748 is a clear-glass inline fuel filter with a 3/8" inlet and nylon mesh element that lets you visually check fuel and trap contaminants before they reach the engine.

This compact, universal inline filter combines a thick glass housing with a 200-mesh nylon element and chrome-plated barbed ends to give older fuel systems a simple visual and mechanical upgrade. Designed to fit 3/8" inside-diameter hoses, the CarBole 9748 helps capture debris that can circulate in aging fuel lines while allowing quick inspection through its clear body. It’s sold individually and built for do-it-yourself replacement on small engines, classic cars, motorcycles, lawn equipment, and other fuel-fed machinery.

How does the clear-glass design help me maintain my fuel system?

The transparent housing gives an immediate view of fuel condition and trapped particles so you can spot contamination, water, or varnish without disassembly. Visual checks let you schedule filter changes before problems escalate and confirm that fuel is flowing correctly after installation.

• Thick glass housing for repeated visual inspection without clouding
• See sediment, water separation, and varnish buildup at a glance
• Quick visual troubleshooting after starting or during priming

Will this fit my vehicle or equipment fuel line?

The CarBole 9748 is made for hoses with a 3/8" inside diameter at the inlet and a 5/16" outlet barb, so it suits many classic and small-engine applications. Confirm your hose inner diameter and match barb sizes before purchase for secure, leak-free installation.

• Inlet: 3/8 in. (0.793 cm) hose barb
• Outlet: 5/16 in. (0.793 cm) hose barb
• Overall length approx. 4.20 in. (10.66 cm); outside diameter approx. 1.07 in. (2.717 cm)

How effective is the filter element at trapping contaminants?

This inline unit uses a 200-mesh nylon filter element that captures fine particles while allowing normal fuel flow for carbureted and older injected systems. The nylon media resists fuel degradation and is changeable when the housing or element shows heavy contamination.

• 200-mesh nylon element traps particulates that cause clogging
• Element included and housed in a clear glass body for inspection
• Designed to reduce abrasive debris that can wear pumps and carburetor jets

Are any fittings, clamps, or brackets included with this filter?

The CarBole 9748 is supplied as a single inline filter only; clamps, mounting brackets, and hose fittings are not included so you can choose hardware suited to your application. Because it features chrome-plated barbs, standard fuel clamps will secure the hose firmly to each end.

• No clamps, fittings, or bracket included — sold individually
• Chrome-plated barbed ends provide positive hose retention
• Use fuel-rated clamps and vibration-resistant mounts where possible

Who is this for: The CarBole 9748 clear-view inline fuel filter is aimed at hobbyists, restorers, and maintenance-minded owners of older cars, motorcycles, small tractors, and lawn equipment who need a visible, reliable way to intercept contaminants. It’s best when you want to monitor fuel condition visually, fit a 3/8" hose, and prefer a replaceable nylon element in a sturdy glass housing rather than an opaque disposable filter.
