Ok, I am sick of the annoying Holley fuelpump on my Duster. Anyone have any suggestions on a good gerotor fuelpump? How many gph freeflow should I have for a 400+hp 340?
I run a lowly Holley red pump and cannot believe how noisy it is. I spent considerable effort building rubber isolators for it -- both between the pump and the clamp, and big rubber isolators between the bolts and the clamp. It has rubber connector hoses to the metal line.
It doesn't really bother me that much, but I REALLY expected it to be quieter
How much of a pain is it to install the intank pump from a dynasty? I found a Mallory 4070M marine pump for $160 from Summit. It is a gerotor style pump. Have not ordered it yet. Not sure which route I want to go yet.
Mallory pumps are great. Very quiet and last a long long time.
Either the 4110 4140 or 4150 would work great for you.

I have a Holley blue on a project car, and as soon as it gets its turn in line that sucker is coming off and a Mallory is going in its place.
I've run my in-tank pump for a ~2K miles without any issues
(except a cracked float that sank to the bottom of the tank:banghead
It is very quiet - barely audible without the engine running.
My original plan was to run a carb on the 5.7l I was installing
and everything was working fine until I wanted to install the hood
and didn't have enough clearance to close it...
The easiest(?) fix was to install a throttle body (~2" tall) instead
of the carb and use the F.A.S.T. EZ-EFI system. The fuel pressure
was adjusted up to 45psi from 6.5psi by changing to a Mallory 4503
regulator and I haven't had any supply problems (although I really
don't drive it very hard...). There was no noticeable change in sound
from the pump with the pressure change.
