fuel regulator fitting sizes
Does anyone know of the top of their head what is the fitting size (AN) on the stock fuel regs?
I'm looking into this fuel reg, but don't know if I will need to adapt the -10 AN fittings ...if that's possible.
Thanks!

Jim,
The stock fittings are 16mm x 1.5. There are adaptors available. I have some in stock to 6AN (which is basically the stock system ID size). They are not really expensive.
Might I suggest that you adaptor down to a -8 or -6 from the -10 on the reg (you'll be doing effectively anyway if you're keeping any part of the stock fuel feed) then you can just run a 16x1.5 to -6 or -8 adaptor.
The Aero regs seem to have a decent rep, and they are rather inexpensive. There are other options, some are expensive, just depends on your needs/budget.
There are other options. I'm trying to remember the title of the thread where we were discussing this one maybe a month or two ago. I'll look.

Greg,
Thank you for your reply!
I believe I am with you on this...
I will use a -10 to -6 on the FPR, and an 16mm x 1.5 to -6 on the fuel line feed. Used on both ends (qty 2 each).
The reason I'm considering using a -10 FPR is because one is available at a reasonable price ($50).
Otherwise I will consider theA 1000-6 w/the -6 fittings. But the price is in the $130-140 range.
So, do you think the aeromotive FPR would fit in the stock location w/the adaptors? Last time I installed an AFPR (928 spec product, $175 ouch), the fit was tight. I believe that product used the stock size base though.
I also like the fact that the aeromotive has a 1/8" gauge port where I can install an electric sending unit, and have it be out of sight.

Jim,
Search the 928 archives for Brendan's post "fluid dynamcis/pressure experts" or just search "Aeromotive". There are essentially 2 threads with that title, I think you'll find more data in the top (newer) one. But I think there may be some stuff in the older one as well.
The thread covers a lot of questions regarding fuel delivery (regs,pumps,line size) that you will have (unless you've been through it already and just needed an adaptor).
HTH,
Greg

Greg,
Yes, I had went thru those threads last night. Lots of good info.
I like to idea of using one reg per rail, esp if I can pick then up for $50. Heck I think the Bosch dampener is $40 or so.
Also, I just wanted to make sure I could make a -10 fit the stock system.
Well, it looks like I may need help with some adaptors...

Oops,
We were writing at the same time.
Yep, I think you've got the plan right. Not sure how the size of that reg will work out in the stock location. I have an 84 as well, just looking, it'd be tight.
You could use a bit more hose, and go to the bulkhead or the fender with the reg.
BTW, the fittings are pretty cheap but 16x1.5 is a bit of an odd size, they aren't *that* cheap. I sell them for about $15 per. They are like selling oil filters - I have them around for the customers who need them, but I make about a dollar when I sell one.
I only mention this because it sounds as though this is a cost-sensitive project. Just keep in mind that any of the AN adaptor stuff runs in the $7-15 range per fitting. Some of the stuff is more. Esp. as you get into bigger sizes.

Jim,
After doing a little math in my head, you might actually come out ahead of the game doing a custom hose with metric on one end and AN on the other.
Don't believe anyone is currently producing a 10AN male o-ring to 16x1.5 metric male, that would be the cleanest way to go. It would just replace the AN male fitting on the reg and you could bolt right in.
Any way you slice it, you are in for ~$80 in fittings to hook it all up into the stock system. Just depends on what's best for you.
PM me if you need offline help on this.

What the heck have you got up your sleeve that you need two 1000 HP fuel regulators?

Greg,
I believe I do need help with this...
I bought the Aeromotive reg w/2 -10 AN inlets , and 1 -6 AN return.
So I need -6 AN to barb style fitting for the return, correct?
As far as the intlets. Did you have any luck finding a -10 AN to metric adaptor? Understood, this will be ideal as I would be able to fit the reg in the stock location.
Otherwise, I think I will have to mount the reg to the firewall.
So how does this work... you supply me with the needed material, and I make custom size fuel lines?
Could you give me a parts list so I can understand what this entails? Costs?
I know this sounds corny, but will all these fittings be anodized in blue or red?? I'm hoping they are available in std finish such as aluminum. I really don't like the obvious custom mod look, but it seems that 'everyone is doing it'.
Btw, I sent you a PM but you mailbox is full. Thank you for all your help with this so far.

Jim,
Sent you a PM, with my regular email if the box is still full. Should be empty, but I thought I did it the other night, and people are still getting bounced.
I'll work up a list and let you know wed/thurs.
As far as colors go, this varies widely. The adaptor I use for AN6 to M16x1.5 (to connect to stock hardlines) is made by one firm only. There are industrial fittings in the same size, BUT they have to be shaved a bit to work, so I just use these. They are steel. A bit heavy, but so what.
That fitting looks factory. Yellowish-gold appearance. Don't think it is zinc-dichromate, but close. Not sure exactly what it is though.
There's a couple different ways to skin the AN10-metric cat, let me look at my catalogs and give you a couple of options. I'll try to find out the colors as well.
Still not quite sure if you are using one reg or two. I do need to know that.
I can do Aeroquip hose with 'push on' fittings (good to 200+PSI) and install an Oetiker clamp (like on the CV joint bellows) just to be really ****. AQP and one of my other suppliers have a hose that looks very 'factory' - black cloth covering - very stealth.
Push lock fittings and a cloth-covered hose would, I think, give you the factory look you are aiming for. There are the more usual racing-looking hose type options, but either a custom swaged (crimped fitting) hose, or the push-lock will I think give the look and functionality you desire.

Greg,
Thanks for your reply. As an aside; I sent this to you via email after you gave it to me. I would have posted to this thread earlier this eve but couldn't (due to admin technicalities).
I picked up a couple adaptors (16mm to -10 AN) from Goodridge earlier today. I will give them a try in the stock location, and hope for a good fit.
At this point, I'm finding it difficult to find a damper for the other fuel rail. 928 spec had them for $60 ($40 a couple years ago). There's gotta be a better way.
What I'm looking for is good tuning. I got a Defi A/F and FP gage. Stock injector are being flowed, new MAF.. and down the road, a wideband O2 sensor.
Being I have an euro s2, I'm limited in my tuning capabilities. So I'm looking for good CO and fuel pressure control. I'm hoping I'm on the right track.
Any help would be appreciated as I'm learning as I go. Thanks!
Sidenote based on previous post; I'm going for 2 fuel regs down the road.
Thanks Greg!

Finished AFPR install
Well, I finished the fuel reg install. I used a single Aeromotive A-1000 AFPR connected to the back of the rails, located behind the MAF. Fits well.
I used -6 AN hose fittings, and M16X1.5 to -6AN adaptors at the ends of the rails (fuel return line as well). The fuel return turned out well as the rubber hose coming from the fuel cooler reaches the bottom of the FPR. w/o using extra hose.
I set the pressure at 43psi w/fuel relay jumpered, and it settles at 40psi at std idle.
Before this mod, my A/F ratio was 15-16 at idle and 13.5 to 14.5 at WOT. Now I'm in the 14s at idle and 12.5 to 13.5 at WOT. Accelleration is much smoother, and seems more powerful. I will tune it further when I have more time (maybe do some dyno time).
The mod cost about $150. Got the AFPR from ebay, and the hose/fitting from Goodridge.
Thank you Greg (Gbyron) for all you advice, and excellent archive info.
Now I'm ready to take Chewy to Sage Lake tomorrow... YES!

Jim,
I haven't read the whole thread yet. I'll try to find time tomorrow. I have to say though you should look for a rising rate regulator instead. I was using a similar Aeromotive and I have found the rising rate reg I switched to be superior. I am using the Bell 2025 (for boosted applications) and it is far superior. I believe they mare a RRFPR for non bosted engines too.Bell regulators

Jim,
Looks nice, very nice! Looks like you have it figured out. BTW- everytime I go to call you, something else jumps in. Been a very busy week.
Andy,
Jim is currently non-force-fed. I can see the usefulness of a RRR in a boosted app without the benefit of some sort of tunable engine management. In a non-blown car relying on the stock ECM- it was mapped using one fuel pressure. You can tune by raising that pressure a bit across the board, or upping injectors a bit, but you really don't want a RRR on a non-blown car. Just introducing another unexpected variable for the L/LH to attempt to correct for. But, on a blown car, they can work.
Let me know when you're coming through.
