This weekend I have been mostly getting bl*ody soaked whilst working on the car!

It looked OK outside so I decided to fit my new FSE power boost valve. As soon as I got the car in a state where I was unable to move it back into the garage the heavens opened ....great

Anyway, I got soaked but the new valve was fitted and with it idling for 10 mins there was no sign of a leak. As I tightened the last hose clip the rain stopped

Got changed and was just on the way out the drive when there was a very strong smell of petrol, lifted bonnet and there was fuel spraying everywhere

Left the car and took the other to the shop and got back home itching to sort out the car. Got changed and went out to the S and by the time I had raised the bonnet the rain was pouring down again

I discovered the O ring seal on the valve had been caught and squashed a little and had some damage, so I fitted the one off the old regulator and popped it all back together this time using PTFE spray which worked really well as it was a tight fit in the fuel rail.

I checked for leaks very thoroughly and turned the adjuster up a quarter turn as recommended and then went out for a spin. The pick up on the accelerator was much better and I got up through the gears and hit 80 a lot quicker, actually before I got to the end of the slip road to join the dual carriageway, part of which I travelled along in a sideways movement as the tail decided to slither in the rain. I headed up the A2 and then back down again and a Corvette passed me which I then pursued for a while until he sped away on a straight section at a speed much higher than I'd like to risk my license for, so I stuck to the legal limit .....honestly I did

As I pulled into the drive the rain stopped chucking down

Lifted the bonnet, no leaks

Well, not from the fuel rail but I had discovered my hood leaks and will need new rubbers around the targa and I also noticed coolant on the garage floor and traced that to a leaking water pump!

It never rains but it pours eh?

Hi Dave,

Yes it does improve the throttle response and makes the car feel smoother.


Hi Bill,

I don't think the insurance company would be bothered too much, it doesn't up the BHP it just gives a better pick up of the throttle, smoother acceleration. I'd be a bit peeved if they asked me for more money.

Was it difficult to fit Kevin? Where did you get it?

Kevin, What did you go for, the horizontal or the vertical ?

For the improvement in driveability you describe, I don't see how you can go wrong for the money.

Yep, which one did you go for? I just sold some stuff on eBay so it will pay for one nicely.

There are two different types depending on which type of fuel rail your car has, mine is the valve that lays horizontally and the bolts into the mounting bracket are vertical.

Cheers Kevin, ok. Not near the car at the moment, but where am I looking for it and how do I tell which type I need?

No problem!

It was a bit expensive for what it is but it does make a marked difference to how the car drives and only took 10 mins to fit, well it would had it not been raining and had I not pinched and split the o-ring seal then had to take it all off again and replace the seal.
