Someone told me that they upped the fuel pressure on their car by compressing the fuel regulator a little.

Basically put a small socket on top of the regulator and put the regulator in a vice and compressed it slightly. (note, not compressing the whole unit)

I'm sure it's bo**ocks, but thought i would ask the question anyway.

Apparently this puts more load on the spring, hence pressure goes up.

Sounds too good to be true

It is one way of doing it but get it wrong, and be prepared to buy a new one. Once done, there's no way of back tracking.

If you don't have the ability to re-map the fuelling, you could end up with a real mess.

If you're VERY careful, you will get away with it, but I'd check what you're doing with a fuel pressure gauge.

Thanks for your honest answer Mark.

Don't worry if i was to do it i would use a pressure guage, i was really just interested in knowing whether it was true or not.

BTW, i will probably speak to you soon, as i am interested in an uprated fuel pump, cheers...Iain

Before attempting get the fuel pump, install, and then check your pressure, you will find that the pump in itself increases pressure by up to 0.7 bar (mines actually a touch more in places)

It is possible to rise the fuel pressure by compressing the std. regulator, a customer of mine did this to his car and I could realy take much fuel away in the fuel map, to achieve the desired mixture.

It´s not my kind of thing, you better have an adjustable fuel pressure regulator. As Bob already told: you definetly need an uprated fuel pump (Walbro), to get a higher fuel pressure as the std. pump hardly can reach the std. pressure.

Thanks for the response.

I am going to get the pump first Bob.

I really just wondered if i was being bullshi**ed by this bloke, you here so many stories down the pub LOL.

Cheers

Damn

If I'd known about this I could have saved some cash tuning my motor

LOL @ Andy

Yeah but, don't think Andy paid any attention to the 'compress slightly' bit......
