Where to mount the fuel pressure regulator?
Spot the common theme 
Just wondering where other people have mounted theirs. Pictures would be nice.
Thanks

wherever you decide, just make sure you can get at it, under the bonet is the obvious choice...

...the reason that you ideally need to fit the fuel pressure regulator as near to the carbs as possible is that your car will probably be quite sharp
on acceleration, and when you think about it, the fuel pump has to push a 'column' of fuel (the fuel in the pipe running up the car)
against the force of the acceleration. Placing the regulator by the tank would mean that the pressure to push the fuel up the pipe is only 2 to 4 psi,
whereas if it is situated by the carbs, you have 7+ psi delivering fuel as close as possible to where it's needed.
Hope that makes up for my last post.....

Stu,
I'd like to understand your point a bit better. Doesn't the fuel pump suck as well as blow, so if the pump is near the carbs then is has
a long length of fuel pipe that it has to suck through in order to feed the carbs. If that's the case then does it really matter where the pump
goes?.
Havng said that, I can imagine that under a short period of acceleration there may be a tendency for the fuel to slide back down the pipe. Does the
pump then act as a barrier and so prevent a loss of pressure at the carbs?

Hi Russell,
most leccy fuel pumps work far more effectively pushing fuel, as opposed to sucking. If you read Northy's other post, he asked about the best
place for the fuel pump, which happens to be as near to the fuel tank as possible, and as low as possible. Most modern cars have the pump actually sat
in the tank, the ideal place, but not to handy for the home builder to accomplish.
HTH Stu.
