I don't believe this will "fix" the problem.. Maybe cover it up a little, but im sure the high pressure will still be there. Well, typically the old 044 surge tank was as simple as that, bolt on, and drive away. It only made a slight difference to fuel delivery (usually because the factory pump couldn't keep up on the first place). I only noticed the problem on this particular vehicle because it started stalling, and idle running like crap.. Scratched my head for a while before it was decided to put a fuel pressure gauge on. KPM sell a fuel reg yes. But Process West SubSurge has a Stage 1 fitting kit which includes a Turbosmart fuel reg mounted to the subsurge, So it simplifies installation and looks the treat! Yeah, I also spoke to kev yesterday about it, because I noticed he had mentioned you could use it even thought I had told him when he first released it we had problems and needed the STG1 Reg replacement kit. He told me the same thing that he will update this website. The single DW300 will be fine, However, I wonder how the twin DW300 fairs.. It could be up there with the single 460.. In my previous experience with the old surge tank, I was one of the original people to run twin 044's, and the Factory fuel reg had the same problem, Althought I do not believe it was as extreme. Either way, with-in a week I fitted a Aftermarket reg to my setup.
