Screw-on Fuel tank caps?

[ray burton]

1959 comanche 250 - the main tanks do not use the Thermos-type caps - Instead they are 1/4 turn screw-on caps.

I cannot find these listed int he Piper parts manual or find any reference to them online.

Can anyone offer some ideas?

(To make thing worse, the left and right main caps work the same way, but are visibly different from each other.)

Hello Ray,
Welcome to ICS and the information Forum.

Don't know about "1/4 turn" screw on caps, but my preceding '62 250, and now my '66 Twin, were converted to T-handle screw on caps, available from Webco.

If it was me, I'd talk to Webco!

Best, Don

I spoke with WEBCO this morning - they said the early comanches had the 1/4 turn screw on caps - and unfortunately, had not had any in stock of quite some time - and no source for them...

Anyway - it is a minor point now, as I have to replace both fuel bladders, replace a main tank fuel sending unit and get the the other three sending units rebuilt..

Looking for a good source for a replacement sending unit (AirParts of Lockhaven can do the rebuild, but they do not have any units to sell me)

Also looking for advise on fuel bladders. Best i can tell, WEBCO, Eagle Fuel cells (Wisconsin), Aircraft Spruce and Knots2U have them.

Oh, and I also need two new Finger screens for the new bladders - turns out they were missing...

any PIREPS on the above?

I have used Floats and Fuel Cells for bladders in 3 aircraft with good results.

I have always had my fuel sender rebuilt.
