I have found this a good setup to have on a high hp engine that drinks alot of fuel VERY quickly

Well thats all about flow rate, not if its a high pressure pump or not.
Have a low pressure pump that will flow far too much fuel, and youll also end up with a surge tank thats always full.

Benen, if you need an engineer talk to this guy:
Aust Technologies:
- Doug Potts
- 8271 4573
- Foundry St, Goodwood

Thats the guy im using and the guy Greg used.
Be warned though, if you havent looked into brakes, etc, youll probably hear some bad news about the upgrades youll need to do to have him sign off on the car.

As for fuel lines, the 1/4" ones just wont do. You will need to upgrade to at least 5/16 or 8mm. 3/8 or 10mm if your expecting to chase big HP later. Also the return line will want to be upgraded, probably 5/16 will do, unless you have a grossly oversized pump.

awesome. I'll try and get stuck into that tomorrow. What's the best way to go about it? take out the old lines and measure them up? or can someone tell me how much i'd need from their experience? Also, much of a price difference between 5/16 and 3/8 lines? also depends what max power i could get through 5/16 lines?

cheers guys
sorry for the dumb questions
almost everything i have been doing is for the first time so im learning as i go.

Ring up a fluid transfer specialist, such as pirtek or enzed and find out from them what the prices are. Probably best to take out the old ones and measure up. Dont forget you will need pressure fittings, and also will need to re-route the pipes for the surge tank. A cheap pipe bender will make installation a lot easier. The pressure fittings can be attained from the fluid transfer place. You may want to get a cheap flaring kit and pipe cutter, makes the whole operation less of a hair pulling excersize. Find out what fittings you will need for the surge tank, fuel pumps, tank etc before you ask for prices. And if anything is threaded, make sure you get the right thread, dont guess. Take it in if you arent sure.

ok, well i started off by measuring up the old lines. With a bit over a meter spare just in case i ordered 9m of 3/8" pipe to cover both lines. The price was only about $1 more a metre so im just putting in 3/8 both ways. Also, from what i can see. the best position for the surge tank is just inside the rear left wheel next to the tank. Anyone else used this position? Other than that i can only see using the boot as a posibility but i'd rather keep the boot space. The battery is already gonna take more of that than i wanted. A pipe bender is about $30 so not too bad but i think a flaring tool is much more expensive? There is a place that is just around the corner that can flare the ends but whats the best way to get this done? bend up the pipes under the car and then take them out and cart them in to get flared?

cheers

taking them somewhere is cumbersome, but if their just around the corner, not so bad. Supercrap auto is a one stop shop for single use cheap ass tool, although my pipe cutter and flaring tool have been around the block a few times, worthwhile investment in my case.
