OK. I have the pillar mount and a Nordskkog electric gauge in the mail. Can I buy a grease gun hose and screw it on to the Shraeder valve on the VP 44 pump? Do I have to unscrew the vavle from the VP 44 pump and screw the hose right in to the VP 44 pump. I hope I can run the hose to the sender unit then the wires through a fire wall grommet to the gauge? Thank you for any help.
