3-2 Conversion - Has anyone done it this way??

WestCoastFords.com


Seems a little cleaner install and less fittings. I like simple stuff rather than the ugly mess of fittings I have now

Well on pre 87 cars the its a 2 port MC so that being said isnt the porp valve already set up for 2 front and 1 rear? All you need to do is get a plug for the sensor.

I have an 88. There are 3 lines going to the MC. My SN95 MC has only two ports, so the 3rd line needs to go somewhere.



This is how the SN95 Mustangs are setup. The extra line goes to where it is shown here. On the 87-93 Fox, it;s a blank plug here. That line goes directly to the MC.


I already have the front FMS plug and an adjustable prop valve installed. At the rear of the combo valve is a shuttle valve. However, after reading up on corral.net, it seems it can be discarded too as the dual-port MC is anough of a safety feature in case of a failure. Basically this way turns the combo valve into a big distribution block.

SO to add the rear port would eliminate the shuttle valve.

I do have an SN95 prop valve too which already has the port tapped. However, i would need adapter fittings for ALL 5 ports as nothing matches what the Fox has.

SO, it's either adapt the SN95 prop valve (gutted of course) or retap the Fox valve as shown to 1/8" NPT and install 1 adapter fitting and put the extra line there.


It just seems like a clean simple install...and yet i've never seen i done til now

I'm trying to avoid double-flaring down in the bay if i can help it. I have the engine in, so i don't want to screw myself cutting a line and then realizing i can't double flare it

FYI,

Page 126 in the PDF has great info regarding Weatherhead fittings and what sizes to use
