LOL......no it's not set on "KILL". Thanks for the advice. You are right,
the number of choices now is pretty amazing. I'll stick to something
fairly conservative.

Hi Matt... It doesn't sound like you have a motor set on "KILL", so I
believe a 140gph pump should be plenty.
All we'd used in racing was a holley 'blue' regulator...fuel entered from
the bottom and exited from both sides... one side
went to one bowl, other side to the other bowl. keeps the plumbing very
simple.
A bypass regulator would work fine also, but I believe is a bit more plumbing.
As far as brands go... you can't really go wrong with any of the main
stream brands... Holley, BG, Mallory, etc, etc...
The choices these days are amazing... I remember back in the 80's... it
was Holley... that was pretty much it for a quality
electric pump. It was almost impossible to walk through the pits at a drag
race and find a car (with a carb) that didn't have
a Holley blue pump... Now it like walking through the isles at your
grocery store and trying to figure out what brand
of laundry detergent you'd like to buy!

Thanks Ron.
From what you're saying, it sounds like 150gph should be more than
enough. The BG280 is probably overkill. I was thinking about using a
regulator with a bypass, so these kits might not be the way to go. It
looks like they come with a basic 2-port regulator.
What about brands? Any opinions on which have the best reliability?
Or brands to stay away from?
Thanks,
Matt

I come from a drag racing background... It's always been thought that
too much is ok... you get yourself a pump that puts out more than you
think you'll need...
like say a Comp140 Mallory pump, or something similar, then regulate
your pressure up near the carb.
Not using enough of a pump will kill you... I'd bought a big block
camaro many moons ago and had run it at the drags before I'd done
really even given it a good going over just to see where I was... every
pass, the motor just fell on it's face at about 1000ft...
turns out the guy had put some $30 electric pump on it and it couldn't
keep up... bowls were dry at 1000ft...
As far as line size... I'd always run -8 from the tank/pump to the
regulator, then -6 to the carb. Supply was never an issue, even running
up to 600hp...One thing to note though...we never ran the single inlet
that splits to the dual feed on our Holleys... we ran two separate
lines from the regulator, one to each bowl...I think at some point,
those single/dual inlets will become a restriction.

Along the same lines as Larry's question. What brands of electric fuel
pumps do you guys use? How do I determine the gph required for my
engine (460hp+/-)?
I came across complete kits at summit and at scoggin dickey. Do you
guys think these are a good value for someone needing the complete
system from tank to carb?

I'm getting ready to run new fuel line from tank to my mechanical fuel
pump (Holley 110gph) to carb. Any suggestions concerning type of fuel
lines to use, and what you are using to filter your fuel and placement
of filter(s) would be appreciated.
Also, is anybody out there insulating the fuel line coming up to the carb?
Thanks,
