Mech fuel pumps can do up to 100bph ish, so you'll be fine.

Only it is not a good idea to have the fuel pump so close to your now modified exhaust manifold.......

With an LCB or 3 into 1 the exhaust manifold moves over to the left hand side, (always when viewed in drivers seat) the mechanical pump outlet is then closer to the HOT manifold, this is a potential fire risk and must be avoided at all costs.
An electric pump, a regulator and a length of pipe will cost you from about £100 upwards, still cheaper than a lot of peoples excess's on their insurance and all the hassle with having an in-car thermal event (fire) then when you factor in the occupants safety..........

Wait, you what? £100 bones, I just used a £20 electric pump of ebay. Works fine, no regulator just got 5psi one for when I had twin carbs.

Yep you are correct adam, too many turbo's as late, I think a solid state pump will do, however a regulator / filter should be used, it is not entirely necessary.

Petrol as a liquid is non flammable....... however as it warms up it releases the highly flammable vapour. A heat shield as a safety device, in my opinion would be like having a stone attached to a rope that you can throw out the window to stop you if your brakes fail.

soo if its such a hazard, why do so many people buy the manifolds and not have the fire hazard you talk about? or why are companys still allowed to sell it without giving major warnings about the problem?
thanks
