Fuel sending unit float
Posted by: miesvan ()
Date: August 31, 2011 12:04PM

I'm looking for a solid float replacement for my sending unit like the gasproof foam floats on newer cars. Anyone have any suggestions? I just want something that floats and I can bend the sending unit arm around.
Thanks,
Dave

The replacement floats are plastic, will that not do the job?

Different float material will affect the reading on the gauge. The float has to be the right size, depending on how high the material floats in the gas. You may have to experiment by bending the float arm to get the right reading. Not a fun task.

i recently parted out a 87 ford F350 and the floats in that were almost 100% identical to the Corvair one.

Yep... Ford floats work. Check vender stock. I don't use Ford parts in my Corvairs.... but have used Drof parts from time to time!

I didn't know that the repro parts were plastic. These plastic floats are the Clark's floats? I cleaned the sending unit and it works fineoutside the tank.

..you're trying to make the float 'unsinkable'?..a few years ago I got a new sender and brass float from Clarks,but the round end of the rod poked a hole,causing the float to fill up; after cleaning the gas out (I poked a hole in each end) I soldered them closed with an electric gun,float on the rod,and coated the whole thing with POR-15..you *could* poke a 1/4" hole in each end and squirt some 'Great Stuff' insulation foam in (it won't fill and cure with only 1 hole..), since the stuff is impervious to gas after it cures..BTW- highly suggest you solder a 'ground wire' on the rod near the resistor pod to the fuel tube,so it will 'flex' with rod swing,,the rod has to go to ground thru the moving contact where it pivots..

Thanks Tom! I wasn't sure great stuff was impervious to gas. Also thanks for the tip on the resistor pod.

..I tested a ball from doing the replacement D-H windows,didn't absorb into the 'spongy' broken surface, or dissolve it after a week in fresh gas..a little varnish buildup on the rod will affect the 'resistance' total that affects the gauge..I also soldered a longer ground on the sender (on the green 65 Monza,sealed tank and new line back to stock FP yesterday) to go inside to an under-dash spot..

The replacements from Clark's look like the float on this sender.
