fuel pressure regulator.....advice please
 

Right, ive just spent 5k on a gearbox and engine rebuild and am in the final stages of running in. The car is booked in for its 1st service and live map with Bob Rawle on friday but im a little concerned about my current FPR...its an FSE jobbie but ive heard these can be unreliable and have trouble maintaining the right pressure...is this true???
I dont want to risk blowing a new engine due to fuel starvation.

What are your views on this and am i just being paranoid????

Ive heard of a few good regulators to buy but how easy are they to fit ?

Does anyone make a complete kit of all hoses,connectors etc ready to bolt straight on to a 98 classic type r.

Just wanna make sure things are spot on being i start giving it the beans!!
