Quietest Fuel Pump - Testing Walbro 255 and MSD Fuel Pumps

The inline pumps of your dreams...
I've been running Walbro 255 (GSL392BX) pumps for years on all sorts of project cars but on our LS swap 1969 VW Beetle (the pig) - I'm tired of listening to the super loud whine of the fuel pump. To fix this issue I recommend replacing it with a MSD 2225 pump. I now prefer these pump because they seem to last well and are substantially quieter. Here's quick review of both electric pumps and we bust out the decibel reader to assist with the myth of different mounting positions makes things quieter. As a quick reminder - remember the Walbro 190 pump is a good inbetween option sound wise!

If it works for you, the simplest solution is the best one! You will know when you do some hard corners, aggressive acceleration/deceleration if the pump gets starved for fuel. I am running dual facet 480532 lift pumps to fill a small surge tank with two Bosch 044 fuel pumps mounted vertically inside. Pretty quiet, reliable, redundant, and capable of 1200hp on gasoline or 800 on E85. Baffled efi conversion fuel tanks with even big fuel pumps inside have issues with fuel starvation on high-G loads on muscle cars. Keep up the great work!

Hope ya'll enjoy the quickness, fastness, as well as cheapness - cheers!

Why not use a seperation tank with the high pressure injection pump inside and a low pressure pump in the main fuel tank?
I really cannot understand how the ls is so versitile it fits everywhere and everything.

Ah the trusty ol’ lift pump! Ya know, I wonder how that changes the calculation on the fuel pump sizing requirement?? Something I’ve never thought to math out

That’s pretty much my question too. Are you thinking of doing an in tank pump down the road or is it more of it works it works and keep the inline pump?

@@MatthewFinlay As light as the car is, I kinda doubt you'd experience any issues with even the most basic of pumps. Other options probably exist as well, such as a replacement tank with the correct flange or modification to the existing tank to accept a fuel pump module (flange installation). Those guys running their cars on the track must use fuel cells to qualify, this might be an option worth considering.

@alexbalke6612 I’m more of an if it works it works kinda gal but I’ve always had better luck with in-tank setups. Cools the pump and quieter. Buttttt working with such odd tank size restraints led me to the custom aluminum tank you see here.
