petrol flight from AUC1534 Grommet


Recommended Posts

Guest TR1957

I owned a 1957 TR3 (TS 18112 LO) with AUC786 H6 carbs.

I have got a problem with this car, because at any time I have some petrol flight from AUC1534 Grommet.

I change systematic these grommets after only 40 miles!

 

I think may be that grommet have some problems with un-lead petrol.

Have you a solution or explanation?

:(

Hi TR1957, and  a very warm welcome to the Forum.   I can't give a definitive answer to your particular problem, but I do know on TR6 fuel pumps, petrol feed pipes, Metering Unit seals all need replacing to use with Unleaded petrol.   The old, original materials get eaten/dissolved by the different constituent chemicals in modern Unleaded fuels.   Maybe Revington TR can advise/supply the repacement U/L compatible seals.   The old type of cotton covered rubber pipe, may appear OK from the outside, but the rubber inside may be rotten,perished or cracked and therefore a fire risk, or swollen inside, reducing flow.
