Flow Measurements on Ewarts Fuel Tap

Are you aware this thread is over slimline tanks that we all know have only one outlet spud?
The second issue is over the off/main/reserve both being on one petcock because again the tanks has only one outlet.
The third issue is that a restrictive low flow rate on single outlet petcocks is detrimental to engine heath at high throttle settings.

No Dave, I didn't realize I had ventured into forbidden territory.
I picked this up on the New Posts link.
And Yes, well aware of the damage at High throttle of fuel starvation.
Which is why I commented the high flow rate of these taps.
I was really inquiring about a source for these taps.
You apparently don't know or won't share.
No worries, I'll simply delete my post and move on, so not to dilute this thread.

TT, thanks for the info.

Received the two from MAP.
The stand pipe is 2.0" from the flat spot/base of the threads. So, with the 3/4 tank mounting pipe, 1-1/4" for reserve- minus the sealing washer thickness. 1-1/2 quarts? in a slimline tank?
I'll be running a die over it and do a fill-reserve test with kerosene.:cool:

Did you try these taps? Did the NPT thread seal or did you cut the BSP thread? I'd certainly like one of these with a 90 degree outlet barb for a remote float bowl/chopped monobloc setup, but not if the thread situation is weird.

It would be interesting to know what fuel taps the JPN race team used on the race commando , whem PW had his Eureka moment of finding out it was the lack of fuel that kept the bike fromm doing 150mph.
