Fuel proof rubber bobbins
Hi All,
Does anyone know of fuel proof rubber mounts, suitable for mounting a fuel pump in the tank?
Is there a tin top (or bike) that uses "in tank" rubber mounts?
I seem to have drawn a blank.
Many thanks,
Paul G

Can't think of any Paul, all of the in tank pumps I know of sit on top of the tank and are held in place by a retaining collar.

Easiest way to mount a injection pump inside a tank is to use the Rover 600 pump assembly which uses a neat bolted flange mounting.
25 & 800 are
similars

Cheers Mel and BT.
I already have the pump. A tad bigger than the Rover one.
Just need a way of mounting it in the bottom of what will be quite a deep tank.
Apparently the rubber that's fuel proof is called nitrile.
I'll keep looking.
Cheers

Hi Paul. If you are looking for suitable nitrile components that may do the trick, most O rings are nitrile. The standard O ring material is NBR 70
(Nitrile Butadene Rubber) the 70 is the hardness. You may also find NBR80 (harder) and NBR90 harder still.
I can't vouch for the resistance to fuel but if you're sure on that you could use large cord O rings either side of your mounting bracket?

Hi Mike,
I'm trying to do this with no metal to metal contact so I'm not sure if I can do that with O rings.
Good info though. That's bound to come in handy.
Hi Rich,
Followed that link, found their website, and emailed them.
Got a reply back this afternoon requesting the weight of the pump (3 kg) so they could suggest the
right "Nitrile" ones to use. Just waiting for a price now. Magic. Thanks.
Cheers to all.
