Fuel feed size

[Yamahaulin]

I'm upgrading to the blown motorsports dual pump kit for my car. I plan on making 600awhp will a -6 feed line support this or do i need a -8?

Never hurts to go bigger.

I got the -8 to feed my 1550cc injectors. You would rather have it and not need it rather than need it and not have it. Also, just a side note, make sure your gastank is the white screw on cap style. I see your awd so you most likely have it. I ordered my dual pump thinking when they said FOR 2G meant all 2g. Turns out FWD has the bolt down pump mounting style.....back then i had no clue and didnt think of checking it.

I have -6 already and was wondering if i needed to upgrade. I do have the screw on style i think. Been too long since i was looking at it, guess i should check again. If it's the bolt on can i not do the upgrade?

-6 should be plenty big especially as the stock fuel rail can support larger hp numbers. If you had an aftermarkert fuel rail and ALL of your fittings are of -8 size then sure, run it but -6 should be all you need and you are only going to flow as much fuel as the smallest restriction will allow. Keep that I. Mi d.

the stock feed line is about the same size as a -6

I'll be replacing the fuel rail as well that way i can do e85, so i could have -8 on that if i needed to.

If you have the bolt on i think the 1g would work but i doubt that you do not have the screw down. And i just machined the 2g one to fit so i cant say if the 1g would actually work.

For gasoline, -6 is plenty.
For E85, go for -8.

Just checked, i do have the screw down style. So guess i'll order the 2g with a -8 feed and a -6 return. Is the Russel ProClassic hose E85 compatable?

Is the Russel ProClassic hose E85 compatable?

Yes* (everything I've read says that alcohol and e85 have similar requirements, and the pro classic is alcohol compatible).

-6 was enough for me on E85

I have no problems with the stock lines.

-6 Made 658 for you?
