Fuel pump noise and location
The biggest reason you see my pump mounted where it's at,is because it was simple.All the fittings have it fairly secure,but I did run a bracket from the pump up to the gas tank strap to hold it more secure.I see you have a Holley pump on your car.It seems no matter what you do,the Holley pumps are loud.When bought new they come with a rubber seal to place between the frame/floorpan and the pump to help noise and vibration.
The Mallory pump I have runs quieter than a Holley.
If you run aluminum fuel lines,they seem to rattle,and between that and the pump noise,the sound carries through the whole car from back to front.
I have braided -10 fuel line on this car,and it helps muffle some of the pump noise too.My car will have 3.5" Flowmasters on it soon,so that will help bury the noise too...LOL!I run a BG 400 pump on my 65 Wagon,and it's a very loud pump.That car has -10 line on it too.I also run a Holley blue pump on it with 1/2 aluminum fuel line for my nitrous plate.So with both pumps running & 4" exhaust,it gets pretty noisey in the car..LOL!
I run 4" BORLA mufflers on it,and I can still hear the BG 400 fuel pump when I'm sitting at red lights.
I find my self saying "ahhhhh" or giving a big sigh after I turn it off...LOL! As much as I love these loud Hot Rods,the noise still seems to wear you out after a long ride.And the fact I'm 46 yeasrs old doesn't have much to do with that,I've said "ahhhhhhhh" after shutting them off as far back as I can remember..LOL!Funny thing is,I've noticed friends and girlfriends doing it almost simultaneously with me when I shut the car & pump off...LMAO!
