Hi! There was a pause in building process because of workshop relocation.
But we are on our way again
I have fixed the issue with sensor adapter by re-machining it.
The problem was on the top side of sensor connection: despite both adapter and sensor had same thread (1/8 BSPT), adapter has a base cone inside, that didn't allow to seal fit properly.
We have made flat base inside adapter with CNC and made an aluminum seal:
JFYI - it works properly now.
I am trying to solve another problem at the moment and I need your advice: fuel reverse line.
My fuel line at the moment looks as follows:
I am using stock fuel pump for carburetor fuel supply.
For N2O fuel line I am using additional fuel pump - Pierburg 7.21440.53.0
It is a low-pressure fuel pump with sliding vane pumping stage.
It's system pressure is 0.15 BAR (2.2 PSI).
My current schema assumes that after arming switch being activated, additional fuel pump begins to pump
This means that pressure between add. fuel pump and fuel solenoid will always increase until activation switch is turned on. And this also means that I should always keep in mind, that I should turn activation switch during ride from time to time.
What I actually want:
I have already made reverse intake in my fuel tank.
I want to add additional reverse valve between add. fuel pump and fuel solenoid that will drop off fuel back to fuel tank in case if pressure will exceed set value.
My problem is that I can't find any suitable reverse valve for low pressure systems. Majority of cars use built-in valve in it's carburetors.
The only similar valve seems to be used in Skoda/Volkswagen
Part number: 049 127 177 C
Do you have/know any appropriate solution for this problem?
May be there are some options form WON?
Thanks in advance. Mike.
