I tore the fuel pump apart last evening.
It only has 15 minutes of run time on
it at max, using non-alcohol gas.
I didn’t see any tears in it, but it
may be slightly stretched / swelled
in the dome area.
This material is very thin, (.015, I think)
and is not fiber re-enforced, but I’m not sure
a stiffer fiber re-enforced diaphragm would
work in a non mechanical operated fuel pump??
The outside of my diaphragm looks a little butchered
on one side. I cut it a little oversize, then tried to trim
it (when bolted together) with an exacto knife….
did not work, lol.
Have a B&S style fuel pump on order, so will try that.
The same one worked good on my 5-1/2 hp Fisherman.
