stupid question ,
Are you running carberated engine
spectra says that there pump can not be regulated down to that low of pressure , and that that pump on that tank wont work on inclines
which i dont really understand having a return line
I ran it with a carb and a regulator for a while before switching to efi. No issues, so I don't know why they would say that.
But, that's hot rodding- you use what you can get and make it work.
