bulkhead fittings on stock gas tank - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Has anybody added bulkhead fittings to their stock gas tank? I want to run a 1/2" fuel line up to my fuel pump and still keep the stock tank. Would I be better off making a small sump tank or just going with bulkhead fittings?

why would you need a 1/2 inch line? You cranking 1200 horses out of your engine?

1/2 in lines???? Wow what kind of motor are you running? I don't see it being that hard to add the bulkheads to your tank though.

No I am building a purpose built E85 engine. E85 uses something like 30 percent more fuel for the same horsepower as gas. 3/8 should work for the motor but I want 1/2 so I have room to expand if I put it on the bottle or something.

The guys on an E85 forum said I should use a 1/2in line. I have read some places where people are running 3/8 with big power and a lot more where people are running bigger fuel line. I just bought a new tank so I figured now would be the easiest time to add on a sump since I haven't put any gas in it yet.
