THE Fuel Pumps Thread!

Another one back from the dead.
It sounds like 12 years on, we're still using the exact same fuel pumps. Bosch 044 and Walbro's 255lph pumps. Is there something better?
I'm looking for a modest 350hp on a EFR 7670 and ID1050X primary and secondaries. It sounds like my oem fuel system should actually be able to handle that, but what would give me a bit more margin and flexibility to expand later? This is all being controlled by an Adaptronic Plug and play ECU.
Thanks!!

I will probably rewire mine today for a constant 12v.
I am unaware of anything "new". I would stick with something tried and proven with a pump.

I would recommend looking at a walbro 450, IRP makes a bracket kit and can have it pre-wired to be a pretty easy install. For peace of mind, I routed a separate fuel pump relay connected directly to the battery, and i haven't noticed any noise from it from in the cabin with the IRP bracket kit. That should keep you safe in case you want to go up to a higher power level later on. Also you should replace your fuel filter if you haven't recently.

If memory serves, the Walbro 450 series is 255lph (litres per hour), which is what I was referring to.
OTOH there is also a high likelihood that I'm wrong, since I'm only a year into the Rotary world/game!
Yeah, my fuel filter was one of the first maintenance things that I did -- what a b*tch to get to!!! above and behind the diff certainly helps keep it out of harm's way, but it's so tough to get to with just a jack and hand tools.

No I actually made it myself running old speaker wire reused from the Previous owner (the fatty stuff they use for the caps or whatnot, think it was like 4 AWG or something) and another non-rotary specific vendor (leash electronics) that has a double fuel pump relay mounted on a board to control two fuel pumps independently (just in case, only have one fuel pump right now and covered the other side contacts with liquid electrical tape)
Also walbro has the 255, which is what you are referring to, and made a new 450lph to deal with ethanol applications, as generally you need more ethanol, as it is less energy dense
Thanks!

About to search for a Walbro 255 install instructions, but will ask here as I do that... anyone know what needs to be fabricated/bought/modified in order to install a Walbro 255 into the stock pump location?
Many thanks!

Awesome - thank you!! Great tool, assuming all the parameters are accurate... :sweat: I don't suppose anyone's had issues with choosing pumps/injectors according to this?

I am running the 1300x primaries with 1700x secondaries (injector dynamics for both) and it idles smoothly I mapped out my setup a couple years ago, before the 1050x came into existance, and it was the smallest . Basically ID and Bosch (collaboration) set a new generation of injectors that are able to be larger and still have good idle control. Honestly the 1050x will be great for those power levels
