New S3 fuel sender is mirror image of original?

Hey all!

I'm switching out my in tank fuel pump and sender assy; the old one just had a few too many little issues and the gasket is passing fumes even though it was new. Fuel float has gas in it, etc. My issue is the the new Centerline unit has the float mechanism on the opposite side as the original. Have you guys installed this with out issues? I don't want the float assembly to hang up on anything. It seems like it wouldn't matter, but I thought that I would ask. Photo...

you do sometimes wonder why aftermarket parts just can't be like the originals!

I'd say as long as you can fit it so that the float is on the same side as, and parallel to the battery it should be ok.

remember too, the filter sock needs to be fitted so that it fits in the small baffle at the bottom of the tank.

Thanks. The filter sock shouldn't be a problem. The old one was; I put in a new pump 2 years ago, and the filter socks would not fit well over the nose of the pump, so they kept popping off when I put the assembly in! I fished out 3 socks the other day after running the tank low. The pump I'm putting has a better fit, luckily.

Ok, so the power wire to the pump doesn't come with the new sending unit. Of course. Mine needs a new lead, or better yet replaced. I don't think this thing in the middle of my wire belongs there; it looks like a normal wire in my manual. My wire looks to have a resistor or something. Do you guys know if normal wire is fuel-safe? How about PVC crimp on connector, if I decide to keep using the current wire?

thats a good question whether normal wire is fuel submersible....very few places sell in-tank submersible wire, like here...so maybe it's necessary or maybe its just scare-mongering (?)

Thanks!! My search skills suck. I'll try to splice the existing wire and crimp on a new eyelet. If that fails due to old hard wire casing, I'll order the in tank wire. Thanks again for the links.

Well, for future people seeking an aftermarket sending unit, I'll post my thoughts on the sender. The senders out there all seem to be the same, and because the float assembly is tacked to the WRONG SIDE you can't install the basket. IAP even used to claim this.

No worries, if you have a good/new stepped hose, it will hold the pump to the new float assy.
My real issue now is that I tested the float before installing it, and it's not accurate enough for me. The fuel gauge won't read to the full mark, and the gauge doesn't move much until it's halfway up. My original is smooth and accurate, and ohms out fairly steady. The new jumps all over the place and never seems to give the same reading full or empty.

Real problem: I need a float. I can't find a float fs online anywhere, Classic Alfa, Centerline, Vicks, Mr. Fiat; no floats, all the same unit as I have.

I'm thinking that I just bought a $74.50 plastic float

just google fuel sender float (google images is best)...there are lots of universal replacements to choose from

for instance, in UK you can get replacement floats for Smiths instruments (most brit cars) for a few dollars (30mm diam. x 55 mm long)

....what size is the alfa float?

Just measured 68.5L by 27.6mm. I'll take it around today and match it up. Thanks for the idea; I always think my Alfa's thing I need is like a one-off item, but it seems from Google that they are out there, and attach the same way to the arm on the fuel sender assembly.
