Worked on my fuel system a bit this weekend. PITA. Driver's side went on ok, but I had to install, remove, reinstall 3 times to get all my "special" stuff worked out. Passenger's side was about the same but finally got it on. Started the car and gas went everywhere. Passenger's side fuel injector o-rings weren't seated. Remove and re-install, front two quit leaking but back two still leaked. Do it again and only the back one leaked. Take a break, do it again Sunday and found that the o-ring was cut on the back injector. Replaced o-ring and re-installed fuel rail, finally all seems to be good. I'll try to post pics later in the week.

ah the smell of 93 octane in the air.....it..it..it smells like victory.
Glad to hear you got it corrected, waiting for the pics! If you get a chance shoot a pci of your oil seperator/pcv rig too.
thanks

Wow FordNut, sounds really messy,:bigcry: hope you worked out all the kinks. What injector size did you go with ? Thanks.

Stayed with the 60s I've been using for several months now.
Going to the dyno this week for a new tune and needed to try and improve fuel delivery beforehand since my last dyno pulls indicated the fuel system was getting maxed out at high rpms.
Fuel system upgrades last time: twin Cobra pumps, bigger (FG800) fuel filter.
Additional upgrades: straight fuel filter fittings, KB BAP, CPR fuel rails.
This fuel system setup ought to be good for at least 550 rwhp. Not gonna go that high until I get a built motor.
Went by the car wash today, sprayed off everything with brake cleaner then high pressure car wash. Good as new.

Did you install larger lines from the tank to the rails? I read in either MM&FF or 5.0 that the lines from the pumps to the fittings outside the tank (the lines in the tank) were a restriction as well. I think they changed to Focus pumps in a Mustang tank. Anyway, they installed something like -8 or -10 lines inside the tank and saw an improvement. With the MM tank basically on its side compared to a Mustang, I think the same would be true since the internal lines are longer.

The length of the internal lines are less than 8 inches. Switching to a -8 increases the volume of fuel available at all times and is more than adequate for our power levels.

No I did not increase the size of the lines yet. That will come later, hoping what I have now is adequate until I get a built motor. I'll be going with 1/2" stainless tubing rather than -8 or -10 hose.

Here is how the original fuel rails fit and looked, notice the fuel injector is pushed sideways so far it's difficult to imagine how to connect the wiring (they're also blue, which I didn't really want):
http://www.mercurymarauder.net/showcase/files/5/1/8/DSC01210.JPG
I had the mounting tabs modified by cutting them down about 1/8", then had the blue anodize stripped and had silver ceramic put on instead. Here are some shots of test-fitting on a spare engine:

Modified the FRPS by grinding down the sheet metal base so it will clear the manifold without messing with the fuel rails if it needs replacement:
http://www.mercurymarauder.net/showcase/files/5/1/8/DSC01218.JPG
Modified the extra fitting that I had with the fuel rails by cutting off the AN fitting then drilling and tapping it out, added an elbow for the Autometer fuel pressure gauge sensor:

Barely can see them on the car, but here they are:

Here ya go:
This is the tubing to the intake manifold vacuum, it's actually copper and powder coated (I tried plastic but it got hot and soft, then collapsed under vacuum):
http://www.mercurymarauder.net/showcase/files/5/1/8/DSC01234.JPG
It connects to the PCV valve here:
http://www.mercurymarauder.net/showcase/files/5/1/8/DSC01233.JPG
From the PCV valve we go thru a molded heater hose to the trap, notice the red pop-up indicator on the trap which lets you know if it's getting pressurized:
http://www.mercurymarauder.net/showcase/files/5/1/8/DSC01232.JPG
Another shot of the trap, the bracket is 1/8" aluminum mounted under the vacuum canister:
http://www.mercurymarauder.net/showcase/files/5/1/8/DSC01231.JPG
And another molded radiator hose going to the valve cover:
http://www.mercurymarauder.net/showcase/files/5/1/8/DSC01230.JPG
Here is where the opposite valve cover gets its air inlet, the hose connects from the valve cover to the s/c inlet pipe between the MAF and s/c. Notice also in this pic where the coolant overflow tank is located, which prevented me from putting the trap on the passengers side like I really wanted:
http://www.mercurymarauder.net/showcase/files/5/1/8/DSC01235.JPG
Not shown is the drain hose from the trap, which I have located down next to the oil filter with a ball valve so it's easy to drain.

Your copper tube/pipe, where was this acquired from?
Looks good, lots of engineering there, I'm trying to go simple, my problem is the 5/8' pcv line is getting sucked close...not all the way mind you but, enough to make me rethink the use of it.

Home Depot! It looked cheesy until I got it powdercoated.

should be about $20, can't say for sure as it was done along with several other parts and the bill wasn't itemized
Fordnut, good job....
I had a question as I am about to do the oil seperator thing as well.
I bought the oil seperator kit from Steeda and was just going to put it inline between the drivers side valve cover and the inlet tube for the turbo.
I assume that is where the oil vapors would be most detrimental since it would coat the turbo, intercooler, etc with oil eventually.
What is the advantage to routing the drivers side vent through the oil seperator and into the intake manifold and then the drivers side (which is where the pcv valve is) through the inlet side of the supercharger??????
I may rethink my project based on how you did it.....
PS Fuel rails look great also. I will be adding those soon as well. What brand are they??

The Steeda trap is small enough that you should have no problems with mounting and routing. But you gotta empty it frequently. I'm not sure how th PCV system air flows on a turbo setup so I'm not much help here.

The only reason I went from side to side is that the only place I could find to mount the filter was on the drivers side. The passenger side valve cover is connected to the supercharger inlet, there should really be very little flow from the engine to the s/c inlet, only the blowby while under boost (when the PCV valve is closed).

Oil will lower the octane of the fuel too. Also, be careful that the S/C or turbo doesn't suck oil out of the heads when connecting the PCV to the inlet of the blower.

So I guess our setups are very close but swapped to the opposite side.
My turbo sits between the radiator and the engine basically in the center. And the inlet is pointed to the drivers side.
I guess to reword my question, Is there an advantage to route the drivers side 'vent' to the inlet of whatever power added someone is using VERSUS routing the passenger side which actually has the pcv inline....????
I am asking this question while under the assumption that the drivers side is a vent only with no pcv valve present. At least that is the way it was explained to me. Please correct me if I am wrong....

That is true, the driver's side is simply a vent (or inlet pipe). My setup is the same as it no longer has a PCV valve on the passenger's side. No real advantage to one way over the other, I would really have preferred to leave the flow direction as it was if I could have figured out a clean way to do so.

If it helps any, the PCV on my Cobra is on the driver's side. I don't think there is a specific PCV flow direction for these engines. I could be wrong.

As it is with the Mach1, so I figured it couldn't hurt anything to reverse the flow, just creates a rats nest of hoses.

This is a dumb question but I'm not familiar with these cars yet. Are they fuel systems return style or returnless?

Brian, your project is coming out great! Where did you get the fuel rails and the cost? I need to get some ordered fr my motor build. I have the dual Cobra fuel pumps now. For a built motor, instead of increasing the fuel line size, have you considered adding a boost-a-pump. Anyone have any comments here? Thanks.

Oil will effectively RAISE the octane of fuel by slowing the burn rate!!:beer:
Slower burn rate = Higher octane....Works every time. I use a small amount of oil in my gas as an upper cylinder lube and a safety factor for poor gas in winter. A trick taught to me years ago by a fuel specialist and it has not failed me yet!!:bows:
I don't think you want to suck oil into the engine but metered in it works fine.;)

Rails are from CPR.
For fuel delivery the twin Cobra pumps and BAP should be good for 500-550 rwhp, maybe more.
I've got the twin Cobra pumps and BAP. Shortly I'll upgrade the FPDM and fuel pump wiring. When I get a built motor it's gonna be kinda extreme so I expect larger fuel lines and possibly even better pumps (Ford GT Supercar) will be needed. Hopefully those mods will be adequate, but I may need to go with an aftermarket -8 AN type fuel filter. Next option would be a sumped tank and return-type fuel system conversion but I'm hoping to not go that far.
