The Fuel Accessories catalogue covers every part of the fuel delivery system from the petrol tank to the carburettor inlet, with cross-fitment items that serve multiple models alongside the upgrades that allow a more tuned engine to be properly fed. MGOC Spares has supplied E10-compliant fuel-system components since January 2012, ahead of the wider switch to E10-blended UK petrol, so any fuel hose, filter, pump or seal sourced from the catalogue is rated for the current UK fuel specification. The aim is to be a complete fuel-system home, performance carburettors, performance pumps, filters, regulators, hose and the specialist items like fuel cut-off kits and stainless braided hose that round out a proper rebuild.
Performance Carburettors and Carburettor Needles
Performance Carburettors, covered also under Engine Tuning, gather the larger-bore SU and Weber options stocked for owners running a tuned engine. The standard 1¾-inch SU HS4 on the MGB suits the original specification but limits a tuned head; HIF44 and HS6 options open up the flow needed for a Stage II head or a mild camshaft. Weber 45 DCOE sidedraughts are stocked for owners going further. Carburettor Needles is a complete sub-section in its own right, the SU carburettor relies on its needle profile to define the fuel curve through the rev range, and a change of camshaft, exhaust or compression ratio often requires a corresponding change of needle to maintain correct mixture across the rev range. The needle range covers every grade used across the classic B-Series, A-Series and C-Series engine families, with the standard, weakened, richened and competition-spec profiles all stocked for owners tuning their own carburation.
Performance Fuel Pumps and Fuel Regulators
Performance Fuel Pumps cover the modern solid-state electric replacements for the original SU points-type fuel pumps. The original points-type design works well when properly maintained but is the source of one of the most common roadside breakdowns on classic MGs, the points pit and stick, the pump stops, the engine starves of fuel. A modern solid-state replacement fits in the same location, uses the same wiring connection, and runs reliably for the foreseeable life of the car. Higher-flow performance pumps are available for tuned engines that the standard pump cannot support.
Fuel Regulators allow the line pressure to be set precisely, important for Weber carburettors that prefer 3 to 4 psi, where a standard SU pump may deliver too much pressure and overflow the float chambers.
Fuel Filters, Fuel Hose and Stainless Braided Fuel Hose
Fuel Filters cover the inline filters fitted between the tank and the pump and between the pump and the carburettors. A modern fuel filter, particularly one with a paper element and a transparent body that lets the condition be seen at a glance, protects the carburettors from any sediment that years of tank corrosion may have liberated. The petrol tanks on classic MGs are typically internally protected to a far better standard than they were when the cars were new, but a filter remains a sensible insurance. Fuel Hose covers the standard rubber and reinforced rubber petrol hoses to the appropriate UK specifications.
Stainless Braided Fuel Hose covers the upgraded line for the engine bay, where a braided stainless outer over a synthetic-rubber inner gives the visual upgrade alongside protection from abrasion, heat and the long-term degradation that catches out old rubber hose under bonnet temperatures.
Fuel Cut-Off Kit and Carburettor Cleaner
The Fuel Cut-Off Kit is a discreet anti-theft device that disconnects the fuel line between the tank and the pump when a hidden switch is operated. It is one of the most effective deterrents available for classic cars, because a car that won't run won't be driven away, and is virtually invisible once installed. Carburettor Cleaner and Oil, also covered under the Service and Lubrication section, covers the cleaning solvents needed to refresh dirty SU and Stromberg dashpots and the dashpot oil specifications used to set the rise rate of the piston. Across the range, the philosophy is the same: every cross-fitment fuel-system part in one place, with the model-specific applications confirmed at the point of order.
