I've not given this a proper update for a while, but today has been a good day so I thought it'd be good to have a catch up of sorts, although if you follow me on instagram or we are friends on faceache then you'll already have seen all of this.

Ages ago my standard fuel pump died, which I replaced with a Walbro 255, when I removed the tank the flare fitting on the supply line was massively tight, impossible to undo in situ so I had to remove the whole line up to the fuel filter.

unfortunately this kinked on refitting and I wasn't happy with it.

as I intend on running a bit more power I thought it would be wise to upgrade the fuel system to suit

so I bought a few AN fittings

(EARL's and Speedflow

- I actually prefer speedflow over any other AN fitting on the market, but the earls stuff is high quality too and works out quite cheap if you buy it from summit racing) and hose and replaced the line from the tank hardline

(which already has the same ID as a

-6 hose) to the Fuel filter like so:



which attaches to the existing hard line with an Earls 5/16th to AN6 compression fitting



and to the filter with an m12-an6 adapter.

I then gathered the rest of the parts I needed



a flow matched set of Siemens DEKA high impedance 80lb

injectors



some injector height adapters



and a generic

"hks style" top feed fuel rail.

.

(more on this later)



the final piece of the puzzle was a Tomei fuel pressure regulator and gauge from RHDjapan

I then fitted all of the above

(a couple of weeks ago) completing the

-6 line from the other side of the filter, to the new rail, the return from the rail runs over the top of it and then to the regulator which is mounted on the leading edge of the passenger side shock tower, right next to the coolant filler cap.

I really wasn't happy with the way the injectors fitted.

.

due to the grommets on the top of the height adapters being quite squishy

(technical term.

.

.

)and the lower O ring on the injector to head adapter being firm the grommet was fully compressed when the rail was tightened up which left the injectors not tight against the head.

.

I really didn't want to risk a massive boost leak, or worse a fuel leak so I sacked the cheap fuel rail off and decided to buy a proper one.

.

more money deposited with RHDjapan saw this thing of beauty in my hands



which is a proper SARD fuel rail, only

£150-ish delivered too, which makes it cheaper than the Racer-x and Wolfkatz rails, it used all three mounting points on the head unlike theirs and it's got a 1/4npt port on it too so I can mount a fuel pressure sensor directly to it in the future if I feel like it.

the eagle eyed amongst you will see that sard supply hard plastic spacers to replace the rubber grommets on the injector height adapters, coupled with that and the fact the injector to head adapters are better the injectors now fit really well, they seal perfectly against the head and I've got absolutely no concerns about fuel or air getting out of somewhere it shouldn't.

so this afternoon I dragged myself into the garage and this happened



it all went back together, I bypassed the injector resistor pack and altered my injector scaling on the ECU and it fired up, one tiny drip of fuel from the rail-FPR line which just needed nipping up and all is good.

to say I'm happy is an understatement, it runs great, idles perfectly and now I have a fuel system that is good for more power than I'll ever make with the car
