I know it sounds like a simple device but why would i need one, and what do they change? effects on fuel pump?

Any info appreciated

What other mods??? There is one already in your efi car..Or do you mean an adjustable fuel regulator ??? Yes o/k for fine tunning..
It can put pressure on fuel pump to deliver enough fuel with high presure and high volume if you are using a fmu with std pump on a blown motor...

You are still running the stock 19lb injectorsaren't you? What you will probably find is that with full throttle it will probably be leaning out. With normal driving the EEC can compensate and keep the AF ratio constant, but at full throttle it can't. The Adj. FPR will allow to bump up the fuel pressure so at full throttle it gives more fuel, if that makes sense.

ahh i see, i did get my car dynoed recently and the AFR does lean out at top end, and it feels when you drive it looses a bit at top end. The adjustable FPR's i've looked at on VPW are like 500 bucks, are they the only ones?

btw i still do have the 19lb injectors...
mods are manifold,73mm MAF 65mm TB,2030 cam, ported e7s

I got a Kirban AFPR shipped out form the states. Going on most of the mustang forums they tend to be the best and are fairly cheap too. Anyway I am happy with it. I got it from JD's Performance, and they were happy enough to sent it out to me. All up it cost about $200 including shipping etc.

have a look at summitracing at the Aeromotive regs.. they bolt on the stock fuel rail and replace the std one. about 109 US.

I was going to get the Aeromotive regulator, but there are lots of reports by mustang guy's of their seals failing causing fuel to be dumped into the intake manifold. Unusual because Aeromotive products normally have a really good name.

Whats wrong with Malpasi units sold here??

ok say i was to get myself a malpasi adj. regulator and an uprated fuel pump for my 5L Au Fairmont, does anyone know whether that would make any noticeable improvements to power/acceleration with just those two mods as it would be spraying a finer mist with the standard injectors still inplace therefore burning more fuel and burning with more intensity over a broader section of the piston??!! Sorry if i made it sound complicated...

Would not make any difference. The only real use is to stop it leaning out when you have got quite a few other mods done. All that running higher FP on a stock engine will do is make it run richer than they already do which will cost you power.
