Fuel system questions. Boost-A-pump/stock fuel lines for engine swap
 

Hello everyone, I have a few questions about the stock FRS fuel system and modifying it to run at a higher fuel pressure. I've already tried searching this information and couldn't seem to find it in the service manual.

I'm doing an engine swap and I am trying to use as much of the stock fuel system as possible.
The FRS has three fuel lines in the engine bay and I wanted to know if anyone knows which lines are for port and which lines are for direct injection and also where they lead to.

I've looked at fuel pump installs and I only see two fuel lines connected to the pump in the tank.


I'm trying to swap to a 3SGE which needs to have a 62psi fuel pressure while the stock frs fuel pump is regulated to run at 58psi.
I will also be getting a FPR and making it into a return system.

The data provided by Deatschwerks shows that the fuel flow will not drop drastically if it's increased a few psi.

So I'm thinking that I would be able to use a Boost-A-Pump to increase the flow to a constant 68psi and having the FPR regulate it for the engine.

I've heard really good things about the Boost-A-Pumps and I feel like this might be better than installing a new fuel pump in my situation.

Bump! Anybody know where I could get this information?

The fuel canister has an internal regulator. You need to delete that and run an external unit. Might as well run a full blown 485 pump and regulator delete setup.

I'm most likely going to be getting the full blown return line kit with the regulator delete,
but would I be able to bump up the voltage and continue to use the stock fuel pump?
I'm not planning on turboing my car soon so I think the stock fuel pump would be enough.

It looks like for the cost of a boost-a-pump you might be better off just using a DW pump and an aftermarket pressure regulator, you'll be damn close to that price and not running the stock pump outside of it's recommended voltage range.
