Replacing Filter housing with y-block

[TooMuch03]

My truck has a regulated return fuel system, so the stock secondary fuel filter housing and fpr are no longer necessary. I left it in place for the oil filter. Now that I have installed a BPD oil cooler and filter, that oil filter is no longer necessary either. I want to remove the whole housing and replace it with just a y-block in the fuel supply lines and a straight through fitting in the return line. Does anyone who has done this, know what size fitings I need on the y-block and return line?

I'm sure I could take the whole housing in to the aeromotive dealer and get the right size, but I'd rather not have my truck down for that length of time, and I can save by getting what I need on line. Thanks in advance.

I saved this link for when I have time this spring to put in my AD2 that's been sitting here since June! (I'm a slacker!!). This may give you some ideas.

Thanks lilpooh. That helped a little. At some point I'd like to redo my fuel system like what they were talking about in that thread with an A1000 and Baldwin filters and all braided stainless lines. I am just looking for someone to tell me what size fittings I need on the y-block to eliminate the filter housing.

Maybe, I need to explain my current setup a little better. I have a FASS 150/95 drawing fuel from the tank (it has filter and water separator, and removes air supposedly). The FASS feeds the stock OEM fuel pump, which should last a while since it's getting clean fuel and doesn't have to work very hard. From the OEM pump, I have all stock fuel lines up to the OEM filter housing on the engine. Then, the regulated return system comes off the OEM filter housing, stainless lines feeding the heads, then from the back of the heads, stainless lines to the aeromovtive regulator, then stainless line back to the OEM filter housing. From the filter housing, I have the stock return line.

Right now, the system is a little over-complicated and redundant, but it works well. I have two regulators. I want to remove the stock regulator and filter housing. Later, I will remove all of the stock fuel lines and go to all stainless like I said before. I am wondering if anyone knows what size fittings go into and out of the OEM filter housing?

Pretty sure the return line fitting is straight cut metric 14mmx1.5.
PM me later today, I have all my parts sheets at home.

I have the entire fuel system ready to install, just need to find the time.
