Yeah when my fuel pressure was at 90psi I was using heaps more fuel and you could smell it through the exhaust and and was dripping un burnt fuel out the exhaust as well lol it sucked but I put a fuel pressure gauge in front of the fuel rail and found out the pressure was way to high so I started by changing the fuel pressure reg and no change then decided to take the walbro in tank out and put the stock one back in and bingo all fixed back to around 60 psi on idle
