Engine/Transmission (1998.5 - 2002) 12mm- 8AN line fitting?????

[GWall]

we put our own fuel system on my truck and i need the fitting that is 12mm into the injection pump, and on the other side of the fitting it fits into an 8AN fuel line. anybody know where i can get it, it is just the strait adapter fitting , not a 90* or anything, just strait 12mm-8AN adapter and i cant find it anywhere. thanks, Greg

I am pretty sure I have some of those fittings I got them from Rod at wildcat diesel, that is now out of business. I would think that some other vendor would have them for custom fuels sytems

-8an? -6 is plenty for 750rwhp.

the part number is RUS-670510 from Summit but it is 12mm to -6

-8an? -6 is plenty for 750rwhp.

As Keith said, -6 is what you want, we use -6 to feed the injection on a 820 HP race motor, -8 is used on the oil/coolant lines.

Yep I think -6AN is good going to the injection pump, but -8 between the tank and the LP isn't a bad idea.



I'm not sure if there is such a thing as a -8AN to 12mm adapter.

You might try these too, I've been looking at them for some changes.

I have few if you still need them let me know. .

I have them, you can get them from jegs and summit. I have -8AN, it's not too big. I still run the stock fuel pump too even with mach 2 injectors and a comp I don't see pressures below 13 psi. The volume in -8 AN lines sure helps on the steep hills I think.

When I was shopping for fuel line parts at a local Aeroquip distributor I took a measuring tape and compared the IDs of -6 & -8AN fittings. The inside diam of the -6 fitting was just over 1/4" and the -8AN was 3/8", so I went with -8AN since the -6 isn't much better than stock.

I found some from a hose shop that sells Parker fittings. I was replacing one that I got from Wildcat and broke. The ones from Wildcat had a larger I. D. than the ones from Parker and I would go with them if you can get them. Also, hold the fitting with one wrench when you tighten the hose to it and you will avoid breaking it off in the V. P. like I did.

Guess it depends where you get them.
