Help with upgraded fuel system

HI All,
 
Picked up a mk1 Escort. Just fitting a type 9 to it now and plan a full upgrade of the 1600 xflow in it including twin sidedraught webers etc, stage 3 burtons head, bore out the cylinders etc. etc.
 
Anyway I would like to upgrade the fuel system. Install a fuel cell, electric pump of some sort, braided lines etc. I've never done anything to the fuel side before and was wondering exactly what a good setup is or if anyone can point me to a build that may be what I am after etc.
 
Thanks heaps, hope to put up a build thread shortly.
 
Cheers,

Shags

    I'm not 100% sure if this applies to Xflow but with my 150rwhp Pinto on twin 45's, the standard 1.3L MK1 escort fuel system was more than sufficient. Just put a Malpassi fuel reg between the fuel pump & the webers. That's it.

    A behind the rear seat shaped alloy rally tank always looks impressive and still leaves some useable boot space.  Perhaps one with an in built fuel well would be good to avoid fuel surge when the level gets low. Twin 40 sidedraughts look good too. It would need to be a fairly high spec x-flow to get the best out of these and I  wouldn't go too large in the chokes otherwise it'll be a bit lazy at low revs and you will lose driveability. You want to ensure fuel pressure is around 2.5 to 3.0 psi & most electric pumps will need a regulator to control this.  Get  someone  who really knows webers to do the carby tuning, someone familiar with these engines and who pays attention to part throttle/light load jetting & response not just wide open throttle horsepower.
    The T9 also enables you to fit a slightly lower diff ratio which will improve acceleration performance but still keep cruising revs down.

    You must live next to a petrol station.

    My old prepollution mk 2 (2lt, small tank) used to go thru tanks of fuel like it was going out of fashion. I was only running a 40DFAV and I was forever running out of fuel (petrol gauge was dodgy)



    The car was dyno tuned after the motor was built, and it really wasn't that bad. More fuel capacity would have been better but I was trying to make a point about how a lot of fuel systems are completely overdone when the factory mechanical pumps & reg with factory sized lines will support big power.

    You can try to find a Capri mk1 tank and install that, tho the parcel shelf will need hacking and welding.... If I knew that when building my zetec mk1, I would've spent the cash and bought a Grp4 tank and stand. Mind you tho the tank looks like it belongs there , only draw back was the filler needed to come out of the C pillar.

    Fuel lines and mech pump are way up to the job of feeding twin 40s, I had a pinto that ran 114kw/wheels on std fuel system.. It span to 8900rpm no problem.

    I've never had any drama running dcoe's or idf's on standard gear. If you want to use an electric pump I was advised by guys on the site to use a tachometric relay to cut fuel if the engine stops for any reason. Found a lpg gas safety switch was the cheapest, easiest way to do it...
    Cheers Drew...
