That's "asshat's" job... he does it in every thread. For a 53 year old, you act like a 10 year old.
Yes,it takes longer to fill a bigger line if it's empty. Once it's full,the size of the line doesn't matter. The only thing that matters is does your fuel system supply more fuel than the motor can use. You don't need to be concerned about your line being too big.It will take a beefy single to keep that -8 full under the demand of a full weight10.0 Buick on ethanol.

kidglok said:I wish there was a hanger/sender available to fit 2 deaschwerks 300 pumps on it, i would trust that over anything.
..... I know,not believe,that Nick would never recommend the installation of more than one fuel pump in any car or vehicle powered with an internal combustion engine. .....
You don't have to worry about me being rude or calling names. Everything you've stated sounds correct. jasjamz was concerned that his supply line was too large for his pump,not too small. He was concerned that his pump wouldn't be able to keep his large line full and feed his motor. I've seen others voice this concern. Hydraulics don't work like some think. If the current pump is able to feed the current motor enough fuel to keep it happy with a -8 line,it would still be able to feed the motor all that it needed if the line was the same diameter as a 55 gallon drum. I see that you also know this to be true.Not entirely true..i know - semantics, but the size of the line impacts your friction loss which affects your pumps supply.... . If you go large enough, your friction loss will be negligible and after a point going larger won't help (or hinder) your performance due to the pressure regulator which restricts flow to generate the pressure you need.... You could have a pump that could supply all the fuel in the world, but if the line size is too small you'll get too much friction loss and the pump won't operate at the flow rate you want....Along the same lines is why two pumps don't give you twice the flow ...There is more to it than that, but in a nutshell line size does play a role in your pumps performance....just wanted to clarify to potential readers - not looking to start anything other than a healthy discussion...
I know.Why do you get so angry when I recommend a doublepumper to someone. It's a wonderful way to supply fuel to a motor that needs a lot of fuel.Not sure of the exact number, but I do know there has been more than 2 dozen I have installed, and ran one in my car for a few years.

Does anyone know if anyone has ever tested the stock fuel system to see how much friction loss we get at various flow rates? The output charts provided by pump manufacturers don't mean an awful lot if you don't know what type of losses your fuel system will consume..... Its probably not all that relevant since we have enough folks on here with proven success with various configurations to know what works or not, but i was just wondering....

This may not be exactly what you were asking for, but someone tested the pressure loss of the stock feed and return lines.
