Fuel pump flows

[hallsie]

Has anyone got some indication of fuel pump litres per hour?
I'm looking at a 5 bar 145 lph pump??

Hi Stu...Is this a trick question?...If its 145LPH then there is your answer....

[hallsie]

But will it be enough?

[mrzigazaga]

For what...Lawn mower....2th scale model of a king tiger tank with full battle rounds...Generator.....Taimar...350i?

Stu, these any help....

Thanks Paul...Interesting knowing that the pump is pushing just over 3 litres a minute...Be interesting how much of that gets sent back to the tank...I guess that equation would be calculated by MPG x LPH...Then you would know how much fuel it takes to make you smile...

I've got a standard boggo wedge pump and it's feeding 287bhp no issues

5 bar is more than enough for a Wedge...2.5 bar is the recommended...36-38psi at WOT.

Let's say you do 10mpg at 150mph, that's 2.3 mi/l, and 2.5 mi/minute, so pretty much one litre per minute, but at the rated pressure.

Of course, most of it is recycled to the tank.

Another reason that the tank isn't filled with crud - not only does it get slooshed about, but it's all passed through the filter about 4 or 5 times on average.

Higher flow rates help a little in keeping the fuel cooler, as more is recycled via the tank and hence kept cooler, as it's not sitting in the engine bay.

I have the standard Bosch pump (5 Bar rated) on the 500 Gredge using the bigger 4 Bar regulator and red top injectors and it has coped admirably to date.
