Sporti & Daytona Fuel Level Sender Replacement?

[Weegie]

Taking off the tank on the Magni 1100 (Sporti in a dress) the fuel tap eventually couldn't take it any more, got 2 new replacements on order from Setin Dinse (the second is for the Hi Cam bike).

The fuel level sensor on the bike hasn't worked since I got it, probably a previous owner cross connected the polarity at the tank connector which apparently destroys them.

Anyway I know it's a thermistor unit and I've read a few of the threads on the topic, including @Lucky Phil repair. I've got some cheap thermistors on order from AliExpress, but in the meantime I came across this on the Stein Dinse site.

Installing a superseal plug (for the electrical connections) won't be a problem and I know that this type of float switch was used for some other Guzzi models I believe the Cali was one.

The fitting on the tank is an external M20x1 and wondering if it would fit (that's the same size as the fitting on a standard Sporti tank).

The fuel tap uses a similar approach where the fitting on the tank is an external M16x1. A collar nut screws onto both the tank fitting and the fuel tap's external threads, with a sealing washer between them.

I did send a mail to Stein Dinse but I've yet to receive a reply and quite frankly I'm not holding my breath

I'll wait for a week to see if SD reply, I've also asked them a simpler mail asking thread sizes.

Tempted to try it as they aren't too expensive and it would save a lot of hassle, time and mess, even if it won't be quite as good as thermistor unit.

Comments appreciated

Make sure you modify your new taps John with Viton/fkm seals or they won't last. I did a thread on it a while back. I don't think the float type sender will work in the v11 tank as the float diameter is too large to go through the std sender tank fitting. I may be wrong but if it's that easy then I'm on board as well.

EDIT..... I just measured to ID of the sender unit adaptor, 14.3mm

Also, his thorough thread on converting the manual fuel tap to a bona fide Lucky Phil EZY GLIDE version:

No reply from SD and being impatient just went ahead and ordered one to see if it works (I doubt it).

With other odds and ends to do on the bikes it would be nice just to get something that's plug & play

I'll post up on the forum on viability when I receive it

Trying to mod the fuel taps looks difficult enough

Thanks @docc & @Lucky Phil

Id mod the taps for you John as now I have the mill the hardest part is easy but the postage would be a killer.

That's very kind of you Phil and I may well take you up on it.

@MartyNZ did post in a drawing of the mod but looking at it, I can't make out the measurements for the positioning of the slot. He did give the length and depth, but I didn't see a datum point on the plunger/spool on where to place it .

If I could get/understand the dimensions I could take the plunger/spool to the local machinists to see if they could carry out the necessary milling operation

Don't think the postage would be any more expensive than having to purchase more fuel taps and it would be great to have them working as they should. I use the taps at least twice a year (usually more) when just doing normal service jobs on the 1100 and the HiCam.

Very much appreciated, thank you

John
