E-Fuel Line Size

I'm in the process of building my 6.0 E-fuel setup. I am curious what some of you have used for as far as fuel line size. I'm mostly stuck on what to use for the engine valley area. I've seen 1/4"/-4 AN and 3/8"/-6 AN. And yes I have read all the sticky's and threads on OBS E-fuel setups

I'm confused. Are you downgrading to a 6.0 and trying to figure out how to plumb the fuel system?

If you're stock just use the metal lines on the frame rail, they are 5/16. I have 200/30's and use those lines and maintain my fuel pressure. I got all my fittings from anplumbing.com. Great prices. The hard line in the valley for the supply us 3/8's though. I Bought hard line to -6 compression fittings to adapt to push-lok hose where i needed it.

I'm doing something similar to alberta 7.3's setup. Pre-filter, 6.0 pump and 6.0 post filter with aeromotive regulator.

That's kind of what I had in mind. Metal lines for supply and pushlok or AN fittings. I know I won't have a problem maintaining pressure, I just don't want to have to re-plumb it when I go bigger eventually. I had saw a few guys regret going -4AN vs. 3/8".

I'm assuming you are talking about the split to feed and return the heads. Nothing else is 1/4. I did -6 to feed the heads and kept the -4 to return into the regulator. From the regulator its back into the stock 5/16 hard line. If you feel like you need to go bigger then by all means but the fuel valve can only handle so much as well. You might have bigger problems if you need to upgrade line size, valve, pickup in the tank, etc. how big are you going? I'm sure the stock stuff can handle the normal hybrid sizes?

Ok that's what I was curious about. The plumbing to and from. I'm going with a setup similar to yours. Stage 2 injectors probably. T500. Intercooler. Etc.

if you are planning on going bigger sometime i would recommend small hybrids. When I talked to Jim at rosewood, he said it be about $600 to make them about any size I wanted down the road (assuming plungers and barrels are still good) that confess with new nozzles of your choice and the machining to a bigger displacement. I still tow and drive with my truck so i wanted very streetable injectors for now. I was going to do 2's but then if I wanted to upgrade I would have to still buy new injectors. Just food for thought.

Ah, for some reason I thought you had dropped a 6.0 into your OBS and needed help with the fuel system. I'll let the others take this one, using a different pump on both my rigs.

I used 3/8" aluminum line with 6an fittings, and 5/16" rubber fuel line with EFI style hose clamps. Dont use the cheapo hose clamps, they will back out from vibes and you will throw a line (believe me i learned the hard way). I have the fuel pump just ahead of the solenoid selector, and a screw in fuel filter right next to the radiator on the drivers side. Adjustable FPR for the return. I also have an autometer oil pressure gauge run off the FPR so i can constantly monitor fuel pressure, just in case the pump starts going out. Super easy setup.

That was kind of what I was thinking. Rosewood is definitely going to be my supplier when it comes time to get them. I only hear great things about them

I can see where you would make that mistake. I ran into an amazing deal on the pump that I couldn't pass up. Plus I like the idea of utilizing oe filters.

I work for Mopar so I use up the genuine $2.50 a piece hose clamps lol. Never had a problem with them yet...*knocks on wood*. That seems to be where everyone is placing theirs but my tank is right in front of the selector so I'm going to have to do a little engineering on the placement of it.
