The hose and fittings are nice quality. Their ability to get stuff shipped out quickly dose not happen.

Quick FAQs
Will this work with my sending unit?
How fine should my EFI filter be?
Use a 10 micron or finer (≤10 μm) filter on the pressure side, plus a coarse pre-filter/strainer in-tank.
Is 255 LPH enough for my build?
For many NA LS swaps up to ~550 HP on gasoline, yes. For E85 or boost, calculate total fuel demand and consider higher-flow solutions.
