Reply With QuoteYes it is the distributor vacuum advance hose and unless the vacuum advance unit is perforated(Common) then it will be better on fuel with it connected.

Was looking under the bonnet and noticed the small hose going to this sensor on the inlet mainifold was broken
I think this is where its supposed to go
Firstly im not sure what the sensor actualy is (looked on rave to no avail) and was wondering if it could be effecting my fuel economy

ah i see, well it looks like the rubber hose end connector is broken. Guess i'll have to see if i can get a replacement one, without buying a whole new vacuum advance unit

Had same issue.
Also discovered my vacuum advance was faulty.
Made a bit of difference in performance, idle and economy.
i went to TRS and had part overnight.
Great blokes.
Best of luck

Yeah im begining to see that the vacuum advance being faulty is a common prob. Come to think of it at idle the engine does kind of hunt around in revs a little. Might be easier to pre-empt it and just replace the whole unit.

Replace the hose by all means, but before you start spending money on a hunting problem, check the connections where the air flow meter and injection leads enter the main wiring harness.
These tend to corrode, causing hunting, erratic firing, and stalling.
Took me 4 years and an embarrassing amount of cash to find this out.
