Tomei Fpr Type S Broken?

[Franko07]

so i just got this tomei reg and im pretty sure its broke but want to make sure im not being a retard....

99% sure ive got the fittings in the right way. What happens is when you go to adjust the fuel pressure im taking off the vacuum line and blocking it so the reg thinks its at WOT and then winding the screw in (I'm pretty sure on almost every fps tightening raises the pressure up) but it seems to make the pressure go down then sometimes up then and it fluctuates then going the other way does the same thing and I cant get the pressure to get any where near 3kg/cm2 (43psi) only seems to sit at 2. Attaching the vacuum line doesn't effect the gauge at all and neither does blocking off the FPR vac line...when you rev the car the gauge goes down as well.

this sounds to me that the diaphragm inside has a tear in it letting more fuel through than its supposed to. Seeing as when I first started the car I could get 3kg/cm2 but wouldn't go any higher no matter where the screw was now I can only get two seems the longer it goes the bigger the tear is probably getting?

I'm sure its not the pumps as I have 040 feeding into 044 and can hear them both on and the car ran fine with stock fpr...

any ideas?

Diaphragm is not torn. If it was then fuel would piss out of the signal port.

It does sound like it's stuffed though.

when i turn the screw all the way down so diaphragm has bottomed out fuel tries to leak out of the casing somewhere on the reg, cant tell where though....

yeh going to return it i think and just put the stock one back on for now.

What's wrong with the stock one?

[Franko07]

nothing really, but i wanted a gauge so i could check fuel pressure and I have two pretty strong pumps so wanted a larger diaphragm reg and apparently these rising rate ones offer better control over stock. Plus you can get dodgy and make your squirters go harder if you want to...

Woftam. Fuel pressure gauge is sooooo easily teed into the incoming fuel line.

[Jordy32]

Are you certain it's genuine?

Any fuel leaking for any reason is bad news..

[Dose Pipe Sutututu]

fuel leaking = fake Tomei FPR

get a Turbosmart FPR1200 or so, even Andy at Adaptronic did some tests and proved that these regulators control pressure very well.

Just my personal experience, I went from a Tomei Type-LJ regulator to a FPR1200 and my AFRs are now nice and smooth also my overall VE table has dropped allowing me to smooth out the values - I gathered the old regulator couldn't control fuel pressure properly.

Yea my tomei had issues asweel going to a turbosmart 1200 now should flatten my afrs

[Franko07]

its genuine, if its not then theve done a damn good job of copying it as it came with tomei stickers tomei instructions and a box covered in tomei shit and wasnt $40.

Either way this is the first tomei product ive bought and were not off to a good start, i just wanted to see if i was setting it correctly and it wasnt some other strange design than others ive used and it looks like its just broken.

thanks anyway!

What about aeromotive regulators? with this I mean has there been decent testing in Australia by others regarding the quality of aeromotive regulators (A1000 Injected Bypass Regulator and Compact EFI Regulator) compared to the Turbosmart FPR1200??
