This has been touched on elsewhere, but I'd like to know if others agree with the theory, first put forward by Chris York, that my leaking fuel pump is causing awful fuel consumption figures. I just topped up Brown Rover after 100 miles of mixed urban/local motorway driving, and it worked out at a thoroughly awful 16 mpg. The last open road trip, also 100 miles, was a very disappointing 20.5 mpg. Had the car still had the BW35 I'd have expected 25 on that trip, but I had the bonus of an overdriven top gear by then, if not yet the torque converter lockup.
The block is rather damp looking behind the fuel pump, and there has been some dribbling onto the cross member, but it's hard to tell just how much is escaping. Could it really be costing me a good 5mpg?
To a certain degree the question is moot, because I have a new pump on its way, but I'm worried in case it doesn't entirely solve the problem. The car was tuned to within an inch of its life just before the BW blew, and it seems to be running really nicely - I'd have expected somewhat better.
