• [Application] 6AN braided fuel line kit widely used as fuel injection hose, LS engine exchange and EFI conversion fuel line.
• [Compatibility] Nylon and stainless steel braided fuel hose kit can be compatible with gasoline, diesel, and other fuels (Except for E85 and ethanol). Maximum working pressure: 750psi. Bursting pressure: 2250psi. Temperature range: -22°F to 248°F.
• [Fuel Filter Regulator] This fuel filter features an internal bypass that regulates fuel output pressure to 58psi. The LS Swap fuel pressure regulator has a built - in 10 micron fuel filter element to ensure that clean fuel is delivered to your engine, thus protecting the engine and increasing engine life.
• [Material] 6AN fuel hose is made of cpe rubber inner, with a layer of 304 steel wire and nylon outer braid; the hose fittings are made of aluminum alloy.

Why Replace Fuel Filter Pressure Regulator?
The LS fuel filter regulator kit can be installed anywhere between the fuel tank and the engine,although it is usually installed in the engine compartment to make it easier to obtain even more even fuel pressure.
58 Psi internal regulator is designed specifically for LS engines
2-in-1 fuel filter and fuel pressure regulator fitting kit.
3/8 inch tube inlet from pump & 5/16 inch return port.
A return line will be routed from the filter/requlator back to the fuel tank.
Adapters are included to convert to common AN6 hose.

Feature:
This filter/regulator assembly is commonly used when adapting return style fuel systems for use with returnless applications.
Designed to operate on 58psi of static supply pressure; Popular for simplifying the fuel system for LS swaps or standalone EFI systems; Capable of flowing a maximum of 255LPH.
Using this filter/regulator between the returnless style fuel rails and your return style fuel lines allows for a plug and play style conversion for retrofitting TBSS/NNBS intake manifolds onto 99-04 return style NBS (Silverado/Sierra) truck and other applications.
Inlet is Male 3/8" Quick Connect; return to tank is Male 5/16" Quick Connect; outlet to engine is Female 3/8" Quick Connect.

Woven net is embedded in the inner wall of the buried pipe to ensure the flexibility andpressure resistance of the hose.
The outer wall of the tubing is smooth and the outer wall is made of composite rubber, which is resistance to aging.

Fitment：
Mostly used in LS system and can be worked with petrol, diesel, oil, hydraulic fluid, pump gas, alcohol, E85 hose, coolant, fuel. Used this on a LS swap, make it easier for the plumbing of fuel system to run all the way from your fuel tank to the engine
