Whos running this nasty fuel system
The nasty system I am looking at is the one think for 1400hp.
Its got a 4203 magnafuel pump big lines and rails and their custom tank.
Think read some things about problems with putting fuel in their custom tank sometimes..anyone running one of these tanks? Any problems with it??
Also who is running a magnafuel 4202 or 4203 pump.They say they are pretty quiet? Is this true..are they pretty quiet. My car is street not track car and want it to be as quiet as possible.
The APS setup is dual in tank pumps. Pricing between the two is not much difference really when you add in the optional 1000hp APS upgrade and its power handling is maybe a bit under what I should get.
So lets hear it guys ,opinions,experiences.

Would rather be a bit more safe than sorry. Also think your intank needs you to send away bucket to get it modified for sender. APS system doesn't require that.
I am not too worried about spending a bit more on your 1400 hp setup. I do remember reading about some guys not being able to put fuel in their tanks but not sure how long ago that was. Is there any problem with putting fuel in your custom tank. Is the tank a straight drop in? And how quiet are those magnafuel 4202 and 4203 pumps. My car is a street car not a race car. An external does seem to be good idea if you have to swap out a pump but I plan on doing the access cover method anyway. Gm should have put it in to start with so not going to be a big deal swapping intank pumps much either.
APS has some problems with its intank hoses. But think they took care of the problem. That was in vettes not the f body system.
I have a walbro now in a stock bucket and if I have less than 1/2 tank my fuel pressure will fall off under boost but not so much when it is full
Should drop tank when replacing pumps we require it as you need to clean the junk out of the tank as to not damage the new pumps.
Darren- Our twin intank setup can be run to just about empty as the pumps are positioned to suck straight off the bottom. Your singe is not the correct pump or the install is bad if you can not go lower than 1/2 tank.

So the magnafuel is the quietest external you have that can take this type of power?
