It took me a while to find it too.

Found it in an Eaton catalogue. Eaton uses the same numbers. so you should be good with any brand with that number.

The guys at the parts store don't know that its sitting on there shelf because they want to sell you a $140 high performance pump instead of a $10 fitting.

Yes. The factory line is regular 'ol 3/8 line with an inverted flare and a nut on the end. The nut is 5/8 thread.

most definatly is I just bought a piece when I swapped my 88 tbi to carb, and the fuel pump ffitting size is 5/8-16. I found it online at autozones website, for the fp I bought, and it's the exact size that comes on the 3/8 hard lines they sell.

some aftermarket fuel pumps use 3/8 or 1/2 npt fittings but stockers are 5/8. Good luck finding a fitting. I ended up cutting an old chrome dual feed holley line for mine, but a short piece of line hard line that is, will work, then you can clamp on rubber, or run it all hard and bend it yourself.

Just to point out, npt sizes are a breed all their own.

Just walk in to a performance shop and ask for FCM2108 its like $10-15. thery will have it somewhere on a shelf.

And it is exactly what you are looking for. I used it for exactly the same thing myself.

k so I just realized that the 8123 comes with a an-6 male to npt male 90 degree fitting on the end. so if you still want to use the edelbrock 8123 then you need the

fitting to turn your fuel pump into a male -6 and then you also need either an

AN-6 female swivel to AN-6 male 90 degree fitting [

XRP X920506
Earls 921106
RUSSEL 614806

or an

AN-6 reusable hose end to AN-6 female 90 degree fitting [

RUSSEL 610160
Aeroquip has ones to and are cheaper but I don't have the part number

You also will need to get a fuel filter or a male to male -6 fitting to attach to the edlebrock carburetor banjo fiitng to AN-6 line as you will notice that it is female and so is the 8123 line. They do that so youy can put either a fuel regulator or filter there as they would have male -6 fittings on both ends.


OR you can get a couple of reusable hose -6 fittings and a length of braided hose and make your own custom hose which should only run you about $40-50 all said and done , a lot cheaper then going the edelbrock route. They purposely do this stuff so they can sell you more crap that really is not necessary.

And I don't know of any online thing in Canada. If you find something online let me know, but otherwise you'll have to make your way to your nearest speed shop.

I was gonna do that Edelbrock 8123 thing to but I just ended up getting some fittings and a length of braided hose and did it myself. Fits better any ways when you do it your self.
