Aeromotive adjustable fuel pressure regulator
Aeromotive remote mounted adjustable fuel pressure regulator, brand new in box, complete with either -6AN threaded or 8mm "push-on" fittings. These are ideal for any performance upgrade, especially suited to parallel fuel rail conversions due to having twin return ports plus a 1/8"BSP pressure gauge port. £135 + £5 P&P, can also supply fuel rail adaptor and liquid filled pressure gauge.

Hi Martin
One small question, do you have any idea how to fit one of these, thought it would be obvious when I saw it but i'm stumped
Also what would be a good pressure to set it at just to drive it to the mappers 40 miles away?

Ross, it's easy really, shouldn't take more than an hour or so, just follow these simple steps:
1. Locate & remove the standard regulator from the fuel rail near the turbo, remove fuel & vacuum hoses and fit the new fuel rail adaptor, turn the brass 90degee fitting to a position like the regulator outlet did before.
2. Mount the new regulator on the passenger side bulkhead or inner wing etc.
3. fit a length of fuel injection rubber hose between the fuel rail adaptor and the side entry of the regulator.
4. Fit the pressure gauge in the front port.
5. Locate the fuel return hose from the steel fuel pipes on the manifold near the n/s strut top. Its the one that doesnt come from the fuel filter (thats the feed), also not the thin one, (that's the tank vent), remove it from the pipe at both ends.
6. Run a new length of rubber fuel hose between the bottom fitting on the regulator and the fuel return pipe.
7. connect a new length of vacuum hose (3mm i/d) from the inlet manifold to the fitting on the new regulator.
8. screw the pressure adaptor on the regulator about halfway in.
9. run the engine and adjust the pressure to 3 bar with the vacuum hose disconnected, re-connect the vacuum hose.
10. Make sure all fittings and hoses are nipped up!
11. Run engine and check for leaks.
12. Go and get it set up professionally in conjunction with mapping.
Here's the reg fitted with the gauge, 8mm push-on fittings and the fuel rail adaptor:

If you need further help just contact me by e-mail or 07837 721986 and I'll help as much as I can!
Good luck!

Hi Nathan,
well it certainly helps as it's required to set up the static pressure, Once it's set then you dont really need the gauge but most people leave them in position so they can keep an eye on it from time to time. I must point out that on the gauge box it says "not for permanant installation" but most seem to ignore this. The gauge is an additional £17.50 if supplied with the regulator.
Of course you could fit an electric pressure sender such as an oil pressure gauge and have it on your dashboard, maybe if you have Defi gauges or something similar.
On my rally car I fitted a second oil pressure sender to the regulator port and put a biased switch in the oil pressure gauge so when the switch was pressed it read fuel pressure instead of oil pressure, that saves having an extra instrument in the car.
Being able to measure fuel pressure is very useful if you get a problem, it's so important on a fuel injected car. If you see the fuel pressure reduce for no apparent reason then you know where to start looking for the problem. If you can be sure that the pressure is correct then you can look elsewhere.

I dont know if there is such a thing as "nomal retail" price. You could pay over £200 depending upon where you buy them from. Mine are supplied complete with fittings, some others arn't. I have a couple remaining at present.

Yes, no problem, I can supply just the gauge, it would be £22.50 shipped, payment by Paypal to mefmotorsport@btinternet.com
