    Default Repairing F355 fuel sender

    Mine is faulty one, reads empty, red light mostly. Any ideas? Occasionally moves but inaccurate, from 3/4 full to empty within the same drive. By the way they are not available new any more.

    Assuming it's not the gauge...

    At a price, you could have one custom-made by a company such as Isspro

    https://www.isspro.com/page.php?page...O_Fuel_Senders

    I had one for an '89 Lotus Esprit made up. If they don't already have a blueprint for a F355, you would have to provide dimensions, number of wires, trigger levels (in ohms), hole pattern, etc. They send you a form to fill out. Unfortunately, the US dollar is quite strong at the moment.

    Thanks, I have sent them an email, see what they say. What kind of price are you talking about? Repair would be a first choice.

    Cheers

    Sorry, my memory is a little fuzzy. It was quite some time ago. It could have been U$300.

    I'd be curious to know what they actually quote you.

    I was just going to ask the same question! Have you made any more progress with a repair?

    I took mine out last year and it had corroded away with the u/l fuel separating from lack of use. Also needed new fuel pump and rubber parts, all disintegrated! Got that sorted but gauge not so good. Annoyingly they were still available then at around £300 ish I think and I jibbed at the price. now 5 times that if available at all........

    I tried to make some new parts for the sender, seemed to work on the bench but when refitted, the gauge doesn't move and the light on all of the time; that was last year and now I thought I have some time to sort it !

    I am working on a solution for this, all being well!

    Please let me know if you would like more info on cost, lead time and what's involved.

    Thanks

    Default NEW 348/355 replacement fuel level sender available soon

    In collaboration with a fuel level sender specialist, we have designed a direct replacement for the original Ferrari item but using 21st Century technology. On initial tests it worked perfectly, with a nice steady movement of the gauge from Empty to Full and the warning light is triggered at around 10-12 litres. Having now completed the design of the fitting parts, it is finished and a prototype will be ready for me to test in the next couple of weeks. Once that is signed off, I will be ordering a batch and make them available to everyone. It will be supplied with a new genuine gasket seal and wiring plug and with the option of an 'economical' specialist fitting tool which is required to remove and refit the unit.

    Please PM me if you would like more info.

    Many thanks, Brian.
