Have you had a fuel pressure gauge on it? I am planning on installing bigger injectors soon and I wanna know if it will pull it down to 0 at wot or not. Im pretty sure im pulling the stocker to 0 with the stock stix, if it is working at all.

Is the spacer required for this pump, like it it is on the bosch one? I got one from OFI and they list it as a direct replacement for the diaphram pump.
Thanks

Anyone know where I might get one of these pumps in Canada. DSG says that they don't have one and that it won't work on my truck. They said that the pressure is too high.
