The concept is simple but the risks are frightening.
An electric pump fitted by a vehicle manufacturer has the electric sparky bits seperated from the
fuel (the stuff that goes bang). The
fuel is in pipes or tanks that stop any
fuel vapour from getting near the pump. Even submersible pumps that late model vehicles use meet this criteria.
Your problem is that you have an open
fuel supply at both ends. One being the jerry can and the other being the
fuel tank inlet. The risk of
fuel vapour igniting is very high if there is anything likely to create a spark.
Spark producers can include:
-The pump if it is not sealed. (They rarely are)
-The pump wiring connections.
-The pump switch.
-Connecting or disconnecting the power plug while fumes are present.
-Static electricity discharge. (even the
fuel flowing induces a static build up)
- Other people doing things around you that you weren't expecting
and there are obviously others. If something does go whoomph, you also have
fuel being supplied under pressure to feed the flames.
I guess that is why you don't find commercial kits, they can't control the use and therefore can't guarantee their safety.
Doesn't mean it can't be done and be done safely but there is a lot to think about.
Kinda explains long range tanks.
Of course you could always try smaller jerrycans.
good luck
