I've got some ID1000 injectors on route, as my current ones are too near the limit.
I will eventually get an external pump and swirl pot, but for the time being, what BHP do you guys think the following will max out at?
-ID1000's
-Sard Fuel Reg
-Parallel rails
-HRC 290LPH fuel pump

I was half recommended to upgrade the wiring which feeds the fuel pump. Is this really necessary? How big of a job is it? Removal of rear/passenger seats, carpet etc? Where is the actual feed from?

If I'm going to add an external pump in the future, is it worth using the current pump feed to control a relay, then take a live feed from the battery, via a fuse (size?), and switch the new live via the relay, and in turn run a new wire to the in-tank pump?
I don't think that will be overly difficult, but where exactly is the feed to the in tank pump fed from?


Thanks for any pointers/advice

 

The feed to the in tank pump comes from the pump relay which is behind the trim panel under the dash on the passengers side

 

Cheers Paul. Do you need to remove the whole dash to access it?


Thanks

 

Nope, just the little trim panel on the left down in the footwell, 2 relays there, iirc the one nearest the bulkhead is for the fuel pump.

There is also a grommet to the engine bay up on the bulk head near there if you want your main pump to be in the engine bay, it's a setup that i'll probably do later down the line once the tuning bug bites

High capacity lift pump in the tank, swirl pot and main pump in the engine bay...

 

Brilliant, thanks
