CNG pressure

[mikebough]

What kind of pressure does cng run at the injecters? Don't know anthing about cng conversions and was wondering. Is there someplace I can info on cng like a manual?

Thanks

Re: CNG pressure

The delivered pressure depends on the fuel system but generally ranges from mid 20 to 60 psig. If you are thinking about using your gasoline fuel injectors, dont try it. They dont flow enough and are not designed for operating with a dry fuel.

Mike,
Some of the OEMs (Ford & Dodge) had rail pressures of 90-120 psi. And I've seen multiport injected kits as low as 26 psi (1.8 bar).
