EFI fuel pump search

[Just puttering]

I have been looking for a replacement in tank fuel pump for efi

I am looking for a 255l/hr

I have searched the forum (using a search engine) and know I have seen posts with info and part numbers and such.

The searches are not grabbing the details I am looking for.

As I narrow down a search on Summit, I end up with 3 options for Walbro all stock flow rates!

Any body have a part number or have a link on the forum for fuel pump part numbers?

Do not use the forum search. Google it for a F5 roadster, if you want to find a thread on this forum.

good luck,

Might want to make sure you get the right inlet and outlet size. I noticed the Summit ad states 5/16" on both.
I would think if you need a 255 lph you would be at 3/8".

I've used this combination for both Coyote builds. Rock solid setup. As stated, with a 255 lph pump you really want 3/8 lines (-6 AN). Ideally for both supply and return. Then you really want a full 3/8 in/out on the hangar. You could use something else for the wiring connections. Just make sure they're made to be immersed in gasoline. I found those Molex ones with a lot of searching and they work great.

Pro-M racing sells the hanger that others have mentioned, its a great piece, but they also sell the 255 or even a 340 pump to support higher hp.

Thanks for the reply's, I may get to pull the pump tomorrow and see what size the fittings are. It has 3/8 lines up front, but I am not sure about all the way to the pump

Well, I pulled the pump and it looks like I have 3/8 out and 5/16 return lines.

I checked voltage at the hanger connector and have 12v. I then put 12v to the pump and even tapped on it for the fun of it, it seems to be dead. The only thing I did not try was checking the voltage at the pump (oops).

At this point, It is getting a new one irregardless.

Be sure the hose clamps on the pump are good quality and tight. A couple of the pinch on clamps have let the hose blow off after installation.
