I started a convo with an engineer over there (Germany). We shall see.

That's great! I've found another source for flow meters in Poland. I'll contact them when I'll get back home. I'll keep you posted.

I got a quote as follows:
1) Art.-no.: 97478334, FCH-m-ALU- 2 x 1/8 IG", 0,05 - 8,0 l/min, 4 x Imp./U

Price: 136,50 Euro / pcs. (1- 9 pcs.)

that is about $179.50 US, per flow device. It puts out 3600 pulses per liter as far as I can tell. I am emailing for clarification on that.
We'd need to arduino a pulse counter and totalizer of our own with this option.

Thanks! I'll see what details and prices I'll get from that polish company. We'll be in touch.

Hi again!
I've found another vendor for flow meters and the good thing is that it has a branch office in the USA

Here's a datasheet of flow meter that should work for diesel in passenger car
DOM x0.5

The price is high, around 400 Euro but engineer that I've talked to told me that they can actually lend me a pair of those for testing.

400 per pair, or each? Looking at those, I'd want them downstream of a filter of some sort.
That means an accessory pump in my situation, I don't think I'd want to drag the fuel through a filter and a meter to get to my lift pump.

I'm also interested in using an Arduino for this purpose. I am thinking about using a MAF. Since it measures air flow and I know the air to fuel ratio I ought to be able to calclulate the fuel consumed. Any reason it wouldn't work?

Thing is, you don't know the air fuel ratio in a diesel. It can consume and pass through excess air quite readily. Watch your EGTs. When they are low, it is not just because power is low.

Well that's not fair! Seems I've got a lot to learn being my first diesel.
