Fuel line size on a '95 V6

I have a friend who swapped a 4.6L into a 95 V6 roller, but he didn't change the fuel lines from the tank to the engine. Are they a different size than a V8 car? He seems to be having a leanout problem, even with a big pump and big injectors. Thanks!

Yes they're smaller, particularly the return line if i'm not mistaken.

Shouldn't make a difference on a stock engine. Is the v8 stock or modded? V6 feed lines are 5/16, and I believe the return is the same. That should be enough for at least 250rwhp if not more.

Its definitely not enough for over 350 rwhp even with a 255 in tank that's for sure. Stock should be fine though.

Wow, sorry I missed the responses guys. I forgot. The 4.6L is mildly modded. Bolt-ons and some mid range Comp Cams. They're running 24lb injectors and an SVT focus pump already. Some people are telling them they need bigger injectors and I'm just not buying that.

I ran a bolt on car with cams on the stock 19s just fine. I'm only running 30lb on my ported head, cammed storker right now. So I don't think the injectors are the problem.

I was just thinking that maybe the fuel line size is the bottleneck.
