I saw your post about the marine intake you were selling - I have a tech question regarding that part. I am doing a marine swap onto my 4.3 but mine did not come with fuel rails. I saw in your post that you mentioned SyTy fuel rails, are they compatible, as-is? Need any fab work? I'm looking to get order fuel rails that will work with the intake and I'm not sure where to start (aside from the OEM Mercruiser rails, which are a staggering $600+). Thanks!
