Hello Listers, 



I thought, I'll ask while the topic is about fuel sending units. I am in the process of building my own HDS wing tanks. Got the sheet metal clecoed in form and now it's time to buy components and fittings.   Is there any reason why I should not use a automotive tubular fuel sender instead of the standard floating lever unit?  I expect a better dampening than with a free floating lever. Some of these tubular senders even have fuel pumps integrated (old BMW 3 series).

I will use mogas on my VW conversion.

Any thoughts?



Carlos, if you read this, did you test your tanks for leakage yet? How did they come out? Are you going to use mogas?



Thanks and



Best Regards from Germany

I used a capacitance type sender in my ultralight and it has been a pain in the butt to keep it calibrated. That's just one isolated experince, mind you,

Peter,



I assume the tubular sender is one with the float

inside the tube?  The one thing I can think of that

might be a problem would be that if the sender is not

perfectly vertical, friction may prevent the float

from moving freely. If you get one and do some tests,

it may be a non issue. I agree that the damping would

be better due to the small hole that the fuel column

is flowing through.



Best regards,
