I haven't bough that particular item from him, but ihave bought a bunch of hoses and other miscellaneous parts from them. I can tell you that they awesome customer service though.
bought it about a year ago, and used half of it /submersible suction hoses for the intank pump. so far so good. also, the rest of the hoses, especially the flex ones feels and looks like oem. i 'll buy his ss brake line kit for my brake project nextime. he's a bit on the expensive side, but, for me when it comes to pressurized lines, i take no chances.
I've got bits and pieces of his fuel stuff, including the metal line between the fuel pump and the expansion filter, which I never knew existed before.
When I started to redo everything back there, I should have saved myself a lot of hassle and just bought the whole damn kit.
