ACUFAB AFPR, brass fitting size?

[Marcus86GLHS]

good point MARK, will try to buy one from the dealer, thanks!

[appaking]

Called the dealership today and asked for the pipe and fitting. They said it was discontinued. This was for a '91 Daytona turbo car. Part # 4418662 if anyone wants to look for one. I didn't ask him to check other years or models.
However, the parts guy said that Dorman has those fitting in their help section at the local parts store, for those who can't get to a junkyard.

I had a problem getting the factory pc to seal. Bought new o-rings (just in case one got screwed up. Went through 3 of those. Shelved the accufab and installed the stock pr to pass smog test. At one time I had called accufab to get a type and size fitting that would work. I thought an a-n fitting might seal and not need an o-ring. I got busy and never called back. Once I pass smog I'll be looking into installing the accufab again then I guess I'll call. Chris

what is amazing to me, as a customer to FWD Perf and TU (both great companies) is that there is no mention of the critical part/fitting needed to adapt the Accufab unit to our cars. i am really disappointed at both vendors for this, i mean a fuel leak at this location could destroy your entire car.

i dont blame Accufab, the unit was not intended to be retrofitted to a 1985 GLH Turbo, but come on TU and FWD Perf. you know that 100% of your customers are operating cars not originally intended for the Accufab unit. why not at least mention the "need to carefully select and install the proper blah-blah-blah part number fitting........"


APPAKING thanx for the info, i am heading to the dodge dealer soon to sort this out, and will post what i learn. dont thread a male NPT fitting into a female straight thread fuel line!!!! i dont care if it does seem to seal ok, you are literally playing with fire.

Update:
I went ahead and bought some BSPT 1/4 to 1/4 barbed fittings from McMaster-Carr. At first I thought they didn't fit any tighter than the NPT fittings. They were bottoming out and the biggest end of the taper wasn't getting into the threads. So I ground off about 3/8 " from the threaded end and it fits tight now. Tight enough that I have full confidence it would seal as is. I would probably put sealer or lock-tite on just to make sure it doesn't vibrate loose. I had to buy a pack of 10 of these, so if anyone needs one, drop me an E-mail.

the correct part number for the fuel line inlet to properly match the Accufab female thread is Mopar part #04418662, which requires o-ring part #04418293.

both of these parts are no longer available. i did a national dealer search for stock, found one dealer that showed stock, but he had already sold the line.

ok, now its off to the GM dealer......maybe theres a GM part since this Accufab unit was intended for GM cars.

and theres always the boneyards, just didnt want to install used fuel system parts.

APPAKING are you saying you used a pipe thread fitting? call me neurotic, but i think that is a very bad idea, if your fuel line leaks right there and you could easiliy have an underhood fire to deal with.

i'll let you know what Mr. Goodwrench has......

Yeah, but you have to remember it is only a 6" long piece of tubing. Go get one from a boneyard, soak it in gas for 24hrs, clean it up a little, and throw it in with as new O-ring from the local parts store. Total investment would be about $5 maybe, and it'd look bone stock. I agree, it would be a used part, but it's not like a used oil filter or plugs, it's just a small piece of metal fuel line.

I wouldn't say just go snag one from a yard and slap it on, but if you clean it up good it'll work and look like brand new. I remember seeing about 5 of these in the local boneyard last week. I need one myself, so I think I'm gonna cruise over there after work today.

The yellow teflon tape used for gas lines works fine for me using a normal NPT brass fitting. It's the fuel return, so if a small piece of tape did get in the line, it won't really matter.

"It's the fuel return, so if a small piece of tape did get in the line, it won't really matter."

MINIMOPAR I was referring to the fuel inlet, not the return, not sure what you are referring to, but i wouldnt want my return line leaking gasoline on a hot engine either.

mixing dis-similar threads might be ok for some applications, like say water lines, but on a fuel line, especially a high pressure, high volume line like our TDs run, its too risky for me at least.

SY2206: great idea, i emailed a friend today to ask about a used one i saw over at his garage yesterday, if i cant get a new part i will do as you suggested.

[minimopar]

I was just browsing the thread and saw the pics of the regulator. The line is the fuel return (supply comes through the rail). Setting an o-ring at the base of the threads will also work. Anyway, I have never had a leak, but touche on the dissimilar threads. They are the same thread pitch, one is tapered one is not. Anyway, I was just making a suggestion.

Marcus,
I do take some offense at your statement about vendors not telling you you need an additional part for the AFPR
This is taken from our on line catalog.
"Our adjustable FPR are made of anodized aluminum, with stainless steel innards to prevent corrosion. These units are rebuildable and bolt in the stock location. The can be adjusted down to 0 psi, and have a burst pressure of 150 psi.
NOTE: 2 peice intake users require a brass fitting for fuel inlet, part number FWD 5-203 ($5) "

Normally if you order from us, and we know you have the 2 piece intake, we sometimes throw it in for free.
Later,
Cindy

[Marcus86GLHS]

CINDY i did see that on your website, i wasnt trying to offend, sorry, but isnt the fitting you sell an NPT threaded adaptor? my issue was that neither vendor gives you the specs on the correct thread type and size, as it looks to be something not-to-easy to purchase over the counter new.

if your adaptor is not NPT thread, can you tells us the full specs on the fitting?

guess i am a p.i.t.a., didnt mean to be. just trying to prevent a fire over here.

Cindy, you may actually want to edit your webiste to say:

"If you're using this AFPR on an 89 or older car,you will also need a brass fitting for fuel inlet, part number FWD 5-203 ($5)."

I have a 1 piece intake on my both my GLHT's and they both need that piece. As you know, it's not the intake manifold that determines whether or not that piece is needed, it's the year of the car. On ANY 89 and older car, whether it has a 1 piece or 2 piece intake, you will need that part.

uh the oem peice on my 89 thread into the accufab unit like a beauty.

[jonnyb]

it's actually 88 and older - 89's have the correct fitting...
