Regarding item 5: Where can the supply and return lines be accessed? Can I disconnect the supply line from the fuel pump after partially removing it?
Regarding item 8: Can I use a mallet and a drift (punch) as field tools to remove the fuel pump locking ring rather than too
One more clarification please.
There are no fuel lines on the external face of the pump/sender. All that is evident is the two prong electrical connector which when removed appears to disconnect the guage and stop the function of the fuel pump. (I cannot hear it) Is the feed line attached to the portion of the pump/sender that is inside the tank and can it be accessed by sliding the pump/ sender unit part way out of the hole to disconnect it?
If this is not possible then How Do I Access the Lines?
