fuel regulator
borg230rover - 11/8/12 at 09:05 PM

Can anybody recommend a fuel regulator, for a bike engine turbo, I need it to be able to lower base pressure down to 3psi and it needs to rise 1:1 with boost pressure. I have looked everywhere but can't locate one with this spec, most only go down to 5psi. Could you supply links to exact regulators, not just sites as I can find loads of them myself.

I take it that you have carbs on your turbo motor hence the need for 3psi as fuel injection would be a lot higher pressure I would assume.
I would look at a regulator from something like a Mini/Metro turbo as I think they were carb/turbo cars, although I could be wrong.

Some thing like this?

As mentioned these only drop the pressure to 5 psi, not the required 3. Yes carbs.

Here you go, 3-15psi with 1:1 increase when referencing boost pressure.

Yes perfect, I would like to try and find a slightly cheaper one but I will certainly keep this as a last resort, I notice you have Mac#1 Turbo, I also have a Mac#1 R1 Turbo carbed what reg do you use and is yours carbed?

Does anybody have a set up for carbs that requires a return to tank fuel line.

Basically I have a fuel regulator that has a return to tank line, I need to know what the best place/way is to connect the return line to the tank? That want cause me issues with restrictions.

My Mac#1 has a fuel injected ZX10R turbo engine, it uses an adjustable Aeromotive fuel pressure regulator similar to the one above.

Where does your fuel return enter you fuel tank?

Easiest way is to use an aircraft fuel connector into top of tank. link. If it's safe for aircraft!!!

I found a photo of my fuel pressure regulator







My tank is designed to accept the standard ZX10R fuel pump housing in the bottom of it



The ZX10R fuel pump has been removed but the level sender is still fitted so my fuel gauge works correctly.

The ZX10R pump carrier has both feed and return lines connected to it, as you can see here, it's not the best of photos. Fuel outlet on the left, return is on the right, they are wrapped in tape to keep dirt etc out.





Bosch 044 fuel pump mounted under the rear diff



Fuel feed and return lines running down the transmission tunnel



Hope that helps
