Fuel Tanks & Cells
Fuel Tanks, Sending Units & Fuel Cells
The fuel tank is the starting point of every fuel system — and on classic trucks and vintage American vehicles, it's often one of the first components to require attention. Decades of service, ethanol-blended modern fuels that attack older rubber and accelerate internal corrosion, and the degradation of sending unit components mean that many original fuel tanks are operating on borrowed time. Getting the fuel storage and level sensing system right is fundamental to a reliable, correct-reading fuel system on any build.
With 125 products from Brothers Trucks, Classic Instruments, Holley Sniper EFI, and Earl's, our fuel tank range is particularly strong on correct-specification replacement and upgraded solutions for classic Chevy and GMC truck applications — the backbone of the resto-mod and hot rod truck market we serve.
Replacement and Upgraded Fuel Tanks
A fresh fuel tank is often the single most cost-effective improvement to an older vehicle's fuel system. New tanks from quality manufacturers are manufactured from aluminised steel or stainless steel with internal surfaces resistant to the ethanol content in modern pump fuel — eliminating the internal rust, varnish deposits, and contamination that progressively degrade older steel tanks and damage fuel pumps, injectors, and carburettors downstream.
For classic Chevy and GMC trucks from the 1947–1987 era, we stock correct-application replacement tanks in original-equipment specifications, allowing a straightforward drop-in replacement that restores correct fuel system operation without modification to fuel lines, sending unit connections, or filler neck arrangements.
Fuel Sending Units and Tank Senders
The fuel tank sending unit is the device that converts fuel level into an electrical signal for the dashboard gauge. When it fails — typically through corrosion of the resistive element or float collapse — the gauge reads incorrectly, either stuck on empty or full regardless of actual fuel level. Correct sending unit replacement requires matching the ohm range of the sender to the gauge it's paired with; mismatched senders and gauges produce incorrect readings regardless of both components individually being in good condition. We stock sending units matched to both classic original-equipment gauges and aftermarket gauges where a different ohm range applies.
Fuel Catch Cans — Oil Separation for Modified Engines
A catch can intercepts the crankcase ventilation gases routed from the engine's positive crankcase ventilation system before they enter the intake. On stock engines these gases contain relatively little oil vapour, but on modified performance engines with increased blow-by, they can introduce enough oil into the intake to cause significant intake manifold and valve deposit buildup over time, reducing performance and potentially causing idle and drivability problems. A quality catch can separates oil from the ventilation gases and collects it in a reservoir for periodic draining.
