The following is a list of the smallest fuel pumps I have found that are commonly available. Some specs are lacking unfortunately (ie cc\models vs actual flow rate), but you can somewhat gauge the suitability for your project based on the application it's used for. If nothing else you'll probably find it to be a good starting point. All of the pressure regulators are the "standard" 300kpa (43.5PSI). Displacement ranges are for four strokes of course and I will update the topic as new information pops up.

PWM fuel pressure control will reduce power consumption and remove the need for a return line. PWM fuel pressure control not implemented in Speeduino currently, so you could either develop it, or buy this module from Madhu:

Good stuff. If you can update the first post as more info is added, this could be a great resource for what and how.

Thanks !

Ugh, just realized I can't edit my original post. Does anyone know what the criteria are to add\edit on the wiki?
Anyway while I'm here, I've updated the grid to sort by (Presumed) pump flow rates. If there's a way I cn to a grid so people can copy\paste the P/Ns that would be good.

Also a photo of various internal pumps and the motocycle models they belong to, something you could maybe eyeball.

Fits right in my go kart fuel tank, goes through the filler cap, and it's really cheap. Will happily go up to 5 bar, good flow rate and tested for holding fuel line pressure- passed with flying colours up to 5 bar, 1.5amp draw at 3bar. Did I say it was cheap

What did you do for fuel pressure regulation?

Is there any information about injectors? The parameters of the injector are also very important, such as the opening time, closing time, etc. I hope there can be a table listing the parameters of common injectors for convenient debugging.

There are many thousands of injectors out there in different size and shape formats as well as flow rates. The data information is not all in one place .
Which ones are you interested in?

What pumps do you recommend for small cars? For example, a VW Beetle. Engine capacities 1200-1600. External, of course.
