034 Motorsport Fuel surge tank for Bosch 044 type

Enclosed type fuel surge tank for Bosch 044 type pumps

The 034 Motorsport FP34 is one of the most advanced Bosch 044 fuel pump installation solution available. Beautifully designed surge tank fully encloses a Bosch 044 fuel pump inside a 1 liter reservoir.

Features:

• CNC machined billet aluminum end caps with Viton o-rings for perfect sealing
• Tefzel fuel proof wiring inside can, same as what is used by the OEM’s
• Extruded aluminum body, 4″ diameter by 8.5″ long body, black anodized
• Mounting tabs that allow flexible installation options
• M12 threaded ports on inlet and outlet for nipple or AN connections with the correct adapters. Can maintain the stock check valve if desired.
• Flexible mounting from horizontal to vertical with NO fuel starvation issues
• End cap integrated pickup design ensures that the FULL 1-liter of fuel will be available to the pump

Why you need a fuel surge tank?

This tank fits universally, but let’s take an example from VW / Audi vehicles. Most stock fuel pumps can only flow enough for 200-300HP maximum. This may not be enough for those looking to push their vehicle to its limits. One solution is to install a higher flowing fuel pump inside the gas tank. In some cases this may not always be possible due to special pickups in certain models such as the Mk4, TT Quattro, and R32. Now, this is where a fuel surge tank like the FP34 comes in. It can easily take your stock pump from a 200-300HP capability to a 700HP capability, allowing your engine to reach its full potential. Cool, huh?

Some believe that simply cutting the fuel line coming out of the stock pump and sticking a Walbro or 044 pump inline with the stock fuel line will increase output, in reality this is not the case. By installing a fuel pump in series like this, the fuel flow available to the 2nd pump is greatly reduced. It’s important to ensure that the upgraded pump has an unrestricted feed to the inlet in order to maximize its flow potential. The FP34 Fuel Surge Tank allows the stock pump to fill its 1-liter volume and also allows the return from the fuel pressure regulator to be dumped back into the FP34, this way the 044 can draw from the volume without restriction, providing full flow to the injectors!

More benefits:

• Solid billet aluminum construction, no welds, all o-ring seals
• QUIET operation, FULLY submerged means that no part of the 044 pump is exposed.
• Full 1 liter volume of fuel available to pump, 99% of all fuel is available for pump to use
• Can be mounted in the engine compartment near the fuel rail, or anywhere there is space, fully self contained fueling unit.
• Inlet and outlet solutions to accommodate virtually any installation
• Fuel flow for up to 700HP at pressures up to 90+psi (6.2 BAR)
• Can be mounted fully horizontally or vertically or anywhere in between

Package contains:
Aluminum body and end caps that thread into an 044 or similar pump such as Deatschwerks DW350
3x -12mm plugs that allow various configurations
Wire pass throughs and pre-terminated fuel proof wire
Mounting feet for flexible mounting

Tips for installation

• The FP34 fuel volume runs at 0 pressure, thus the return from the fuel rails should always be directed back into the can, as well as the return to the tank connected so any air can vent to the fuel tank.
• The stock or in-tank pump will be flowing at 0 psi into the FP34 meaning that its flow will be greatly increased compared to the 044 pump inside the tank running at much higher pressures. Fuel pump flow is proportionatly inverse, the less pressure the pump needs to make the more it will flow. Because of this even a low flowing stock pump will flow much more at 0psi, combined with the fuel returning from the regulator, this makes the FP34 a well filled option.
• There are 4 main connections to the FP34: 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 and 4) Fuel output under pressure to the fuel rail/s
• Since the FP34 is a self contained fuel pump system, it can be mounted virtually anywhere, even in the front of the car, where ever there is room for it. It can also be mounted horizontally or vertically and anywhere in between.
• The FP34 should always be mounted with the outlet either horizontal or up to completely vertically towards the sky, mounting the fuel pump outlet anything less than horizontal towards the earth will greatly reduce its active fuel capacity.
• Lubricate the o-rings with light layer of oil before installing
