I am planning on doing a surge tank setup, and I have a few questions. Since the car will be mostly street driven, as a safety standpoint I would like to have the surge tank in the trunk, so if I did this setup, I know I would have to run the outlet line on the post surge tank pump all the way to the front to the fuel rail, but other than the cost of the extra hose, would that work? Also, how does a system like this get wired up? Thanks alot guys.

 

anyone?

 

anyone

 

If I am not mistaken I have seen this done with 2 pumps (usually Bosch). One feeds the fuel from the tank to the surge tank and the other feeds from there to the rail.

 

I am going to use the walbro 255hp intank to feed the surge tank and an aeromotive A1000 to feed the rail.

 

supprised nobody goes this route.

 

Could you explain the purpose of the surge tank to enlighten those of us who haven't heard of one being used for fuel

 

Here is alot of info about it.

Yes running the feed and return to the rail from the trunk will work no problem. You cannot use any of the stock fuel lines unless you plan to seriously modify the stock feed. Obviously, you wont wanna use the stock return.

When you say how would you wire up do you mean electrically or how would you run the lines?

Electrically you can wire both pumps to there own relays to be triggered by the stock power wire. The amt of priming needed will be the same as stock as long as your tank is built properly. The entire point of all this is to ensure you fuel pump actually gets the fuel needed during hard turning, accelerating or braking. If your not using this car in auto X or some other type of racing then this type of setup would really be overkill. The one sweet advantage of this is being able to have a separate fuel cell for race gas with the ease of being able to flip a switch to go from race gas to street gas with little to no mixture of gas.

I am doing it to avoid sumping the tank, because I dont want to risk having my pump being 2" off the ground and driving in a pothole infested state. Also to avoid fuel starvation to the sump when braking after racing. The car will have close to 700whp and used mainly for drag/street. I think it is a much better street setup than a sump.

here is my diagram of how it would be.

 

You not using the "factory return line" like that though right?

You are still going to need to modify your stock pickup to accept a -10 fitting to feed the surge tank. And if you are doing that then you might as well just get one Bosch puller pump and skip on the surge tank idea. Or you could use two Bosch pumps and just T them together. Even with two pumps you will not spend as much as a surge tank setup. If you still are worried about loosing fuel at the pickup then just add some fuel cell foam and call it a day.
