Fine if you don't need your car for weeks....
He doesn't have any stock of modded rails, so I would have had to remove mine, send them off to him, and wait for them to be modded, before finally sending them back !
So I'm just fitting the regulator...
After also giving up on Mocom, RCMS, Scoobyclinic amongst others....
I can't give my hard earnt away ! LOL

P.S. I got my hose and fittings from DT ! One stop shopping ace.

That's the main reason I decided to do mine myself. Most companies that I spoke to said it would take weeks to get all the parts I needed !
Mines been running around 400bhp for a few thousand miles now without any issues

The standard fuel setup means the injectors are fed in series with number 3 being the last in the series to be fed. If there is a pressure drop resulting in reduced flow then injector number 3 can run lean and melt a piston.
With the injectors running in parallel feed,all the injectors are fed the same amount without the risk of one of them running lean.
I'm sure someone else will be able to explain it all better than me

My standard reg failed at around 340bhp.
Uprated reg is a must for applications where an uprated pump is used. No matter what BHP
Not that its stating the obvious, but its seeming to be common place for cars to be running uprated pumps with OE regulators. Something I don't agree with (especially in low bhp applications where the uprated pump isn't needed - but thats for another thread )Inccidentally, the regulator is by piston number 3, so obviously the biggest pressure drop when the reg starts to leak excessively is at the reg itself....no.3

Or don't answer the e-mails or phone calls....
Don't carry stock...
Or carry a kit which includes parts I don't need, so won't pay for !
LOL

P.S. Flatfouronline have some rails in stock (?) for £125, Nice !
P.P.S. Cheers for the info Sharky.

Exactly the same as my experience
One company who I won't name promised me that they would have all the parts in stock and would meet me at Trax @ Silverstone last year,well they didn't show up and when I called them they told me they failed to get all the parts required-nice of them to let me know

I'll get there in the end ! LOL
TBH I hadn't fancied using "mere" hose clips on std solid lines, but the "budget" efforts on here have made me think twice... even if I need to source some more Pro-clamps..
Good job I'm not in a hurry !

RCMS do a kit... but DO answer e-mails.
Scoobyclinic don't stock bits... but do answer phone.
Mocom, neither.
I'm not bad mouthing anyone, but for a whole week I've got nowhere, except on-line with Demon Tweeks.... even if a bit pricy, but progress at last !
IMHO

P.S. We all have problems with T'Internet sometime.

Nothing wrong with budget if done safely! People spend too much on bling bits uneccessarily.

Nice tho'.
My inner "engineer" drives me to a proper solution, but he's fighting my rather more powerful "skin-flint".
As I'm a Yorkshireman...

So just to be sure here, I can replace my hard pipes for fuel hose WITHOUT flaring the cut ends of the rails? I've got my IM off at the moment, and tbh I'm not bothered about whether it's parallel or not - I already run a reversed flow system which works OK anyway - but it's more that I want to move all the fuel plumbing out from under the IM so that the inlet pipe is completely separate from the IM.

I used 2 quality fuel hose clamps on all the ends and it's all been fine so far

Cool, I'll break out the pipe cutter then. The way I've got it figured, is I'm separating the fuel system from the breather and emissions systems under the manifold. So that means the pipes to the charcoal canister and will be done in hose laid over the engine and the breather crossover pipe deleted entirely (i.e. freed from the manifold and replaced with hoses going round the outside of the IM). All the fuel piping will be re-done entirely in hose but stay captive with the manifold still. The idea being I want to be able to get the inlet pipe onto the turbo first without any interference from the manifold (and its 10mm spacers) then just sit the manifold on top and connect up the fuel hoses and regulator.
Has anyone else done what I'm planning to or is there some blindingly obvious reason why I shouldn't? There's so much plumbing to do I'm sure I must have overlooked something.

The fuel tank breather is now VTA by adding some hose and terminating it by the wishbone.

Well I was going to leave my manifold silver, but seeing it in black makes me think perhaps I'll give it a go. Battleship grey wrinkle finish would look good if I could get some.

but isn't that why they fit fuel pressure regulators so that the pressure stays constant through out even if it drops.
