Fuel Sending Unit Details - Tape and Sleeve
« on: May 11, 2020, 07:45:21 PM »
For the 3/8" single fuel line on my '69 Z, the pipe terminates at the top of the rear frame rail then connects via a 5" rubber hose to the fuel sending unit. The sending unit's fuel pipe is secured, in part, by the fuel tank strap where there is a pinch point between the tank and strap (see photo and AIM diagram). At this position the sending unit pipe is protected by a rubber sleeve covered by tape (see AIM Parts #5 & #6.). During the disassembly of my project I took photos of the sleeve and what was left of the tape. I assume the tape is a crepe style as was used elsewhere during the assembly process. Does anyone have better information on the tape used on the sleeve?

Excellent photos and details Jim, good foresight in taking the time to document this detail originally and thank you for posting.

From the photos it appears the tape is plastic-electrical or asphalt based?

The Lighter strata layering (Wisps of white or beige) suggests paper or cloth (?) rather than "pure" vinyl or rubber

Here's a better shot of the underside of the tape.  I couldn't take a close enough photo to show the fibers but the thin hair-type fibers run perpendicular to the length of the tape.  Also included pics of the tape that holds the sending unit wire to the top of the tank - it's the exact same stuff.  Wanna know more details on my tank, let me know - I have pics of the mastic glue smears used to hold the pads and pics of the steel supplier stencil also.

More good photos, thanks. Jim, does the tape look like anything that's commercially available currently?

Looks like a typical fuel line clamp, used farther down the line.

The REPOP clip was put on years ago when a Kinked Fuel line rubber hose was presenting a fuel delivery issue, the clip must have slid over during the removal. Tank was removed and on the ground at this point.

I have never searched for a filament type tape like that.  I compared my electrical harness tape to the black side of this tape and while different, you had to look really close to see the difference.  Given the location of this part, I just wrapped it with that.

On corvette vacuum headlamp hose bundles and on a few places on the wire harness there is a tape used to bundle things together which appears on the adhesive side like friction tape but has a black smooth front surface, (like harness wrap or electrical tape but this black smooth front is only a fraction of the thickness of electrical tape or harness wrap.)  (not to be confused with the fiberglass filament tape used at the vacuum "T's".)

NO ONE ON THE NCRS boards had found a suitable replacement as of last year.

I replaced a couple of sections and used friction tape of the correct width combined with 1/2 mil black plastic cut to the correct width as the tape . 

Does this appear to be the same type of tape as on the sending unit wire?
