If I'm not mistaken, they are talking about the fuel rail on the backside of the engine under the intake manifold. If you're replacing injectors you might as well replace this anyways bc it's not recommended to reuse it after removal.

Hi,

Could you please tell me the part number for the SI hard line?
I can't find a part description with "hard line" name.
Does the SI hpfp and hardline upgrade requires any other parts to replace?
After attempting this upgrade, I would not advise it. For it to be ideal, you also need the Si HPFP base and for the money spent there is almost no difference. The Si Intake cam alone is a good upgrade with raising the fuel ceiling. With multiple options for the Accord 2.0t fueling upgrade from Axion industries, JSR Engines, and FK8TD you're better off putting your money towards one of these upgrades. The Si Intake cam is also needed for the Accord 2.0t upgrade.

Mine is all sorted out and been running great. I ended up back to a stock non-si hardline which has a larger opening than the Si hardline and kind of in between a modded and stock Si hardline.

Did you have issues with the drilled Si hardline ?

Not with the Si hardline, I had a non-Si line modded by a pro and think it was too big and was having a little inconsistency in pressure. I had ran a mildly modded Si hardline, but it ended up not sealing after swapping HPFPs back and forth between non-si/Accord/Si multiple times trying to dial in the fuel system. Instead of buying another Si line and paying to modify it, I just threw a non-Si hardline in. I didn't notice any difference with it and the mildly modded Si line in the end with the current setup and already wasted money on an Accord 2.0t HPFP so trying no to throw anymore money at it.
