In Facet Low-Pressure Fuel Pumps for Carburettors, you’ll find low-pressure electric fuel pumps designed for carburetted engines, typically operating around 0.27–0.55 bar (about 4–8 psi). The range commonly includes Silver Top and Red Top variants, offered as standalone pumps or kits. If you want to compare universal pumps across brands, open Fuel Pumps - Universal. Filter by stock and price, sort the list, then confirm NPT ports and the stated delivery pressure on each product page. Pick the right pump for your carb setup and place your order.

Facet Low-Pressure Fuel Pumps for Carburettors – low-pressure electric pumps for steady carb fuel delivery
These Facet low-pressure fuel pumps are aimed at carburettor fuel supply, where you want stable fuel flow at modest pressure rather than EFI-level rail pressure. You’ll typically see Silver Top and Red Top options, available as pumps or kit versions to simplify installation.
Based on the product descriptions, the operating window is in the 0.27–0.55 bar range (roughly 4–8 psi), and the pumps can be installed inline in the fuel line. The updated solid-state design and a serviceable internal filter (under the end cap) are practical features for regular checks on classic and motorsport-style builds.
Technical Basics
Model choice mainly changes flow rate and delivery pressure: the Silver Top Road description lists 114 l/h with 0.27–0.38 bar, while Silver Top Competition is shown as 132 l/h with 0.41–0.48 bar. The Red Top Works is described at 151 l/h and 0.41–0.55 bar, which can suit higher demand carb setups when regulated correctly.
Ports are a key fitment check: the listings state 1/8 NPT inlet/outlet for Silver Top pumps and 1/4 NPT for Red Top, so your fittings and hose tails must match. Kit versions may include a spare filter, hose adapters and rubber mounts, helping reduce extra parts sourcing.
Important: carburettors are sensitive to excess fuel pressure, and the product description recommends using a fuel pressure regulator to avoid leakage/overflow at the carb. The same description also notes the pumps are not recommended for motorcycle engines.
Selection Criteria
Start with your carb’s pressure requirement: if you need gentler delivery, a 0.27–0.38 bar type option (e.g., Silver Top Road) is a sensible baseline, while 0.41–0.55 bar (e.g., Red Top Works) can offer more headroom when paired with a regulator. The goal is stable pressure at the carb, not “maximum pressure”.
Decide between pump-only and kit: a kit can be convenient when you need compatible adapters and mounting pieces, but you should still confirm the hose size your build uses (for example 8 mm vs 10 mm adapters where specified). Minimising extra reducers and sharp bends helps keep delivery consistent.
The product pages mention “up to” guidance in hp (around 150–240 hp depending on variant), which can be a helpful pointer, but matching real demand, line size and filtration matters just as much. In practice, these are carb feed pumps (sometimes called a lift/feeder pump), so plumbing quality is part of performance.
Installation & Maintenance
The descriptions note inline mounting with a two-bolt bracket, so plan a secure location that protects the pump while keeping it serviceable. Use proper pre-filtration, keep the inlet side unrestricted, and support hoses so fittings and NPT threads are not stressed by vibration.
After installation, check for leaks, then set the fuel pressure regulator to your carb’s requirement. If your model has a serviceable internal filter, clean or replace it periodically—restriction here can cause lean-out symptoms or hesitation under load.
Safety: fuel system work is a fire risk; depressurise, ventilate and only run the engine once everything is fully leak-free. If you hear unusual pump noise or see unstable delivery, inspect the filter, fittings and grounding before replacing parts.
FAQ
Are these Facet pumps intended for carburettors or EFI?
These are low-pressure pumps intended for carburetted engines in the stated bar/psi ranges. EFI systems typically require much higher pressure and a different overall fuel system design. Always decide based on the listed delivery pressure.
What pressure ranges do Silver Top and Red Top versions provide?
The product descriptions show Silver Top Road at 0.27–0.38 bar, Silver Top Competition at 0.41–0.48 bar, and Red Top Works at 0.41–0.55 bar. You normally set final carb pressure using a regulator. Match the target to your carb manufacturer’s specification.
Which ports do I need to match before ordering?
Listings state 1/8 NPT ports on Silver Top pumps and 1/4 NPT on Red Top. Choose fittings/hose tails that match your hose size and avoid stacking reducers. Confirm any kit adapters (e.g., 8 mm or 10 mm) match your plumbing.
Why is a fuel pressure regulator recommended?
Carburettors can leak or overflow if fuel pressure is too high. The product description recommends a fuel pressure regulator to keep pressure controlled at the carb inlet. This improves consistency and reduces the risk of fuel seepage.
What’s included in kit versions (often marked with a “K”)?
The description indicates kits may include a spare filter, hose adapters, rubber mounts and an earth strap. This can simplify installation when you don’t already have compatible mounting and connections. Always confirm the exact contents on the individual product page.
Choose the correct pressure range for your carb, set it with a regulator, and complete your order.
