Description

Dinan Upgraded Fuel Pump Assembly Kit for BMW | F2X | F3X | N20 | N55With increased power comes increased demand on the fueling system to satiate that demand. The stock fuel pump is incapable of delivering consistent fuel flow at low fuel tank levels for high output applications under heavy load resulting in the possibility of inconsistent power delivery when the car is pushed. Dinan's upgraded fuel pump enhances the pump's ability to draw fuel, and allows full flow of fuel to the engine during high demand operation.

With increased power comes increased demand on the fueling system to satiate that demand. The stock fuel pump is incapable of delivering consistent fuel flow at low fuel tank levels for high output applications under heavy load resulting in the possibility of inconsistent power delivery when the car is pushed. Dinan's upgraded fuel pump enhances the pump's ability to draw fuel, and allows full flow of fuel to the engine during high demand operation. This means that at no time will you suddenly experience a loss of power due to inadequate fuel supply and you can push the car hard continuously during a track event or other high demand application without fear. Perhaps best of all is the Dinan modified fuel pump can be properly controlled by the stock DME resulting in no faults or warnings on the iDrive. Just consistent power all the way to redline.

This is for the complete modified pump assembly but an upgrade kit is also available for those that wish to modify their existing fuel pump.

Note: RACING-ONLY PART. NO DINAN WARRANTY.

Features:

  • Allows consistent fuel flow to the engine during high demand operation.
  • Stock DME can properly control the Dinan modified pump so no faults or warning are presented.
  • Dinan components consist of CNC stainless steel adapters, stainless clamps, and high quality automobile grade submersible fuel hose.
  • Includes new modified fuel pump and O-Rings which must be replaced during pump installation.
  • No other modifications needed.
  • NO DINAN WARRANTY
  • RACING PART ONLY

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
