Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) 3.7 l Roadster advice please

Out for a quick spin today, stopped to fill the car up with the 'Miles to empty' reading 100 miles...I managed to get 26.6 litres into the tank. Isn't the tank supposed to be 55 litres?

On the plus side, it read 328 miles after refueling but I am not sure how far I'd trust that before I top up again.

Might be worth checking a zero'd trip from a full tank and comparing with miles to go as it clocks down. Maybe worth re-setting average mpg as well as I think it uses that figure to calculate miles to go.

FWIW I filled up this morning at 35 miles to go and it took 45 litres which seems close enough to me.

It makes no difference Richard. Mine dropped 15 miles to go on a 4 mile run as the tank shows under 1/4 but driven miles are 180.
Does anyone know what happens if the ECU thinks the tank is empty ? Does it stop the engine.

Can't believe it would ever do that John, what would be the point?

Regarding miles to empty reading, it will drop dramatically if you drive hardish especially shortly after an average mpg reset because the latter will drop dramatically as well.

As you can see the fuel level sensing is quite complex and it would only take one of those level sensors to go u/s to really mess it up.

There are reports on the Mustang forums of new cars where the fuel warning stopped the engine despite 1/2 tank.
I can't see the point either & maybe they aren't related.

Well an update on the progress on Belle. Bell &Colvill have been very helpful, MMC have been there usual self.
B&C will fix the fuel gauge even collecting my car from Felixstowe, fixing it & returning it from Leatherhead. Excellent service I think you would agree.

MMC see a 10% under reading speedo as not an issue & anyway it can't be recalibrated they say (Mustang forums say otherwise). But it is legal they say, I thought speedos could over but not under read. You have been warned if you have a 3.7 l Roadster you may be inadvertently speeding.

MMC also advise not to do anything with the throttle pedal that sits (I checked today) a massive 3 1/2 inches below the brake pedal. So so much for a sports car pedal box. I think I'll buy a bit of 2 x4 and work it down to the right dimension whilst Cain works up a solution.

You are correct John. I'm really surprised at the factory's response over that.

For the ARV6 i just made a new pedal, and left the drive by wire throttle box where it was, It was downright dangerous before

Simon,
I agree am looking at that with Cain but if you have solution please PM me the details
John

John, apologies a bit late to this thread, but for reference this is my footwell, at the lowest point of the throttle pedal it's almost flush with the brake, tapering back to approx 3/4" at mid point
