Default Inline fuel pumps

Just curious what inline pumps most of you are using on your conversions. My last conversion I used the Aeromotive A1000 pump, but this time I think that pump is way overkill for a 5.3 with a cam only truck engine. What are some of the fuel set ups you guys are using?

I put a Mallory Comp 250 on mine and it makes so damn much noise that I will probably change it. I can't stand this damn thing.

I took the intank pump out and I'm using a Holley Black electric pump. I've also got two Holley regulators; one for the motor side and one for the nitrous side.

The Holley Black is noisy too

Are are you running a carb setup? I ran a holley red 97GPH all last summer with my setup. No issues and my engine was around 500hp.

I have a Weldon that I used on my injected motor. It's real quite and after some research, I find that it can also be used for a carbed engine. It can be regulated down to the correct pressure. I will be switching to it shortly. If you watch the video I posted, you can hear the Mallory pump come on just before the car starts.

I'm using a Bosch 044 pump. It will support a lot of power and is relatively quiet. The threads on it are straight metric so finding fittings is kind of a pain.

Kinda back from the dead, but....

I'm gonna be running a ls1 with a ms4 on a 150 shot.
You guys think a inline walbro 255 will be enough?
