VW MK1 1.4 TSI Swap Fuel System Hardware Kit

Sourcing fuel system components for your 1.4T swap shouldn't require hunting across multiple suppliers and compatibility charts. This complete ancillary kit consolidates critical hard-to-find fittings and mounting hardware into a single, verified package—so you can focus on the swap itself, not the scavenger hunt.

What's Included

Fittings:

• 1× Banjo M12 to 5/16" barb (Bosch 044 or equivalent pump outlet to engine line)
• 1× Acorn nut M12×1.5 (M12 banjo cap-off)
• 1× Fitting M18×1.5 to 5/8" barb (tank to pump connection)

Mounting Hardware:

• 1× Stainless steel bracket with rubber lining (60mm OD fuel pump mounting)
• 1× Stainless steel bracket with rubber lining (fuel filter/regulator mounting)

Pressure Regulation:

• 1× Fuel filter regulator 6.6 bar (OEM, part number 1K0 201 051K)

Additional Parts You'll Need To Source

• Fuel hoses (appropriate lengths for your application)
• Hose clamps/collets
• Fuel pump (Bosch 044 or equivalent recommended)

Why This Kit

The 1.4T swap requires specific fuel system upgrades to handle boost and flow demands. Rather than cross-referencing part numbers across VW, aftermarket performance, and industrial hydraulic suppliers, we've done the engineering validation and bundled the correct spec components. Thread pitches match. Barb sizes are correct. Pressure regulation is dialed to factory spec.

No guesswork. No returns. Just bolt-on compatibility.

Technical Notes

• Filter/regulator maintains 6.6 bar (95.7 PSI) consistent with 1.4T factory fuel system requirements
• Stainless mounting brackets accommodate thermal expansion and vibration isolation

Compatibility: MK1-2-3 chassis with 1.4T engine swap
