I am going to install the Walbro fuel pump on my 01 but I am not really certain as to where I am supposed to pull my return from the fuel rail. Any info would be appreciated. Pics would be better. Thanks

Either

A) Custom route where you get a return bung welded on the opposite end of the fuel rail and install the FPR downstream of the fuel rail

or

B) I was told that this route works, too, as a way of doing the return style fuel system without having to modify your fuel rail. I can see the theory of how it works, but I can't tell you from a physical standpoint.

I was given this info back in Summer '07, when I was really looking into boost.

Any liquid in an enclosed space acts as a solid (equal pressure in all directions). With the one-way valve on the return line it's an enclosed space. As long as you have pressure you'll have fuel.

Like I said, I know how it works in theory. Fluid dynamics was pretty much everything with regards to my job when I was in the Navy.

I guess what I meant by "physical standpoint" is I haven't personally done it. Poor choice of words on my part

OK I will look into it. Right now I have an aftermarket FPR because its already turbo'd but the PO didn't do anything else to the fuel system. I may just let someone do this one for me. Side note. How many people have used these oil filter sandwich plates?

What is the purpose of running the hose like this? Is this the way it comes stock ( I have not taken mine out yet)

has anybody on here actually done this to their car? I have seen a DIY on clubrsx but would like to see one on a 7th gen civic.
