That makes sense Jake. Pretty sure both your Vanagons have the larger
ID on tank outlet. Plus you wouldn't be prone to using a zap strap.
<grin> No dis to person that did this.  :)

Kinda hijacked this thread a little mentioning two somewhat separate
issues in one breath.

Re Miguels comment on pump cooling:

1. Higher ambient temps seem to contribute to making my FP cavitate
more. (buzzing sound but not as loud as Arborite + trimmer)

Re stock FP mount bracket

2. Mine is stock ('81) If pump not cavitating, (making buzzing sound)
pump sounds normal. (*quiet* whirring)

Of note, my Jetta engine is quieter at idle than air cooled was so the
normal whirring is likley easier to hear.

Pump is near new.

I suggested the DV Bosal exhaust mount (along with some kind of
bracket), as a possible solution to zap strap, rope or duct tape.

<grin>
