I've converted my corsa 1.4 to the x18xe1 vectra engine, I've used the cheap eBay adjustable pressure regulator and I understand 3.8 bar = 55.1143403 psi, now the gauge on the regulator is in steps of 20 iirc, I've got it set to what I think is correct but still not convinced its correct!

So, is there anyway to set the correct psi which runs same as 3.8 bar, or am I better off getting a proper regulator that reads bar?

Cheers.

closer to 56 psi but anwhere up to 60 psi would be ok such a small amount wouldnt be a problem.

No way of getting it bang on? Reason being is car is very thirsty & wondered if this was the cause!

Getting around 85/90 miles to £20!

maybe a sensor is giving up, maf, air temp, water temp, lambda. what gear box you using and how do you drive? my z22se corsa c isnt much better but i drive it quite hard and its using the vectra b f23 box so low ratio in a corsa.

My Fuel pressure was set correctly on my X18XE1 Conversion.
Still drank fuel for fun...

Set the reg to read just under 60 on the Gauge, that should be about right in this case.

If you aren't convinced that the Gauge is displaying correctly, get a different Gauge and try that (no need to get a full new regulator system unless you are certain the Regulator is guffed)

Does your pressure gauge read bar or psi Chris? What miles you getting to a tenner?
