Nice and neat, it normally suits flat wing tanks, and your header also fixes that for 'box' shaped types. I am happy with a continuous filtering of fuel as given by a 2003 Polo fuel filter on the output, with a built in blow off regulator to keep fuel pressure at 3 Bar or 42 psi, cheap and simple and the return isn't a big issue, as it gets rid of air and vapour locking. Do like your idea of check valves on twinned pump setups. My setup was advised by a BMW tech who lectured on fuel injection, used a single Flutra pump, only concern with mine is no input filter to the pump itself, but might put a coarse screen filter to minimise risk.
I was just thinking of doing this to my 701 in the poly header tank. Now I definitely will, thanks. You are very right to mention that aftermarket inline pumps are meant for very high horsepower engines and so have too much flow. Rotax has found a nice way around the dual pump setup though, mounting them in series with bypass to avoid doubling the flow when both are working.
@@Arjuna86004 nope, I have been looking for aftermarket fuel pumps catalogs. Not yet made a choice, I'm bench testing my engine with cheap inline pumps.
Hi Jan, where is the fuel pickup on the "in tank" pump? Can it be mounted sideways? Specifically, How can I mount one inside of each of my (not yet delivered) fuel tanks for my CH-650? I don't think there is any room to have it come through the bottom of the tanks. Thanks!
Disappointing that Viking will not sell the pump separately. I don't need that particular style header tank and was told by Viking to go find the pump on the open market myself.
Jan, I'm impressed with everything you've developed with the Honda engines for aircraft use and wish the Viking 130 was a physically workable option for my little Pulsar III. BUT this fuel system is absolutely brilliant. The weight, cost and complexity of the systems UL Power and others specify for their installations should forever be a thing of the past now that Viking has developed this superior option.

Did you check to see if Viking would sell you a pump separately? I was told a flat no thanks.

Where can I find these tanks?...didn't see on the Viking site...
I the pump fails can the engine fuel pump draw fuel through the pump?
What engine fuel pump ?

Jan, What is the weight savings of going with the new v old from Viking.

Yamaha YZ motorcycle pump. As for me, I'm gonna buy his mini tank, if for no other reason to support small business and help pay for his R&D

Checkout the Viking 90
This guy sounds like your son based on how he talks similar to you. :)
regulator is supposed to be close to the engine to relieve vapor
Very old system. Not at all popular in today cars
In the US, I believe that stopped being the case in 1996 and newer cars. It's been this way for almost 22 years.
Don't forget that this kind of system has a 3 bar pressure. It doesn't form vapor easily.
