injector pressure ?

[troy fox]

was looking at the specs. on a y385t the injector setting says 13.2 mpa +/_0.5 whitch converts to a little over 1900 psi the question is does that sound like enough pressure ,seems low to me 13.2=1914.4 psi are the numbers i am coming up with if i am converting it right ?

Your conversion is correct. Although the tolerance is 72.5 PSI each way.
The pressure seems like it is low compared to newer technology, but these engines and fuel systems are simple basic units of old technology so the spec is an "old time" number.
Probably not the most efficient fuel system, but rugged and reliable. I am always amazed at how much work I can get out of my little 385t engine for less than 2 gallons per hour.

thanks ,guess i was thinking low compared to newer tech.May be why they are so efficient because of the lower fuel pressures , Well we will go with that anyway ,never the less a lot of bang for your buck fuel wise .
