If you're diving into the world of performance tuning for your VW or Audi, you might want to check out the 034Motorsport FP34 Fuel Surge Tank. This isn’t just any surge tank; it’s a well-thought-out solution designed to house a Bosch 044 fuel pump in a slick, compact 1-liter reservoir. What does that mean for you? Flexibility in mounting and, more importantly, optimal fuel flow.

Now, you might be wondering, why bother with a surge tank? Well, the stock fuel pumps in most VW and Audi models typically max out at about 200-300HP. If you're aiming to push that number up to around 700HP, the 044 pump is your best friend. But swapping out the in-tank pump isn’t always feasible, especially in models like the Mk4, TT Quattro, or R32 where the pickups are a bit tricky. That’s where the FP34 comes in—it lets you keep your stock setup while giving you the capability to feed that hungry 044 pump.

Here’s a common misconception: some folks think just slapping a Walbro or 044 inline with the stock pump will do the trick. Trust me, it won't. You’ll end up choking the flow to the 044, which defeats the purpose. The FP34 ensures the pump gets an unrestricted feed, maximizing its flow potential right to your injectors.

Features That Matter:

  • CNC machined billet aluminum end caps with Viton o-rings for a solid seal.
  • Tefzel fuel-proof wiring—this is the same stuff the OEMs use, so you know it’s reliable.
  • Extruded aluminum body, measuring 4" in diameter and 8.5" long, finished in sleek black anodizing.
  • Flexible mounting options thanks to handy mounting tabs.
  • M12 threaded ports for easy inlet and outlet connections—adaptable to either nipple or AN fittings, and you can keep the stock check valve if that’s your jam.
  • No fuel starvation issues, whether you mount it horizontally, vertically, or anywhere in between.
  • Integrated pickup design ensures that the full 1-liter of fuel is available to the pump.

Why You’ll Love It:

  • Solid construction—no welds, just clean billet aluminum and o-ring seals.
  • Whisper quiet operation since the 044 pump is fully submerged, meaning you won’t hear it buzzing away.
  • That full 1-liter volume means your pump has a constant supply of fuel to work with—99% of it, in fact.
  • Mount it wherever you can find space—engine compartment, trunk, you name it; it's a self-contained unit.
  • Fuel flow capable of supporting up to 700HP at pressures over 90+psi (6.2 BAR).

What’s in the Box:

  • Aluminum body and end caps that thread into the 044 pump.
  • Three 12mm plugs for various configurations.
  • Wire pass-throughs with pre-terminated, fuel-proof wire.
  • Mounting feet for versatile installation.

Things to Keep in Mind:

  • FP34 fitting kits (AN or nipple connection) are sold separately.
  • Includes an M12 adapter to help with any discrepancies in aftermarket pump lengths—pick the one that fits best.

Installation Tips:

  • The FP34 operates at 0 pressure, so make sure the return from the fuel rails goes back into the tank, alongside the return to the stock tank for venting.
  • With the stock pump flowing at 0 psi into the FP34, it’ll actually flow better compared to when it’s under pressure. This setup helps fill the FP34 nicely.
  • You’ll have four main connections to manage: 1) Fuel from the in-tank pump IN 2) Fuel vent from the FP34 to the stock tank 3) Fuel return from the fuel pressure regulator 4) Fuel output to the fuel rail/s.
  • Mounting is flexible—just ensure the outlet is either horizontal or pointed upwards to maintain fuel capacity.
  • Don’t forget to lubricate those big body o-rings with a little oil before you install.

So if you’re ready to take your fuel system to the next level, the FP34 is a solid choice that’s built to last and designed for serious performance.
