Viper fuel pump

[OLDCAT]

Question:Why would the fuel pump over the summer or for setting for four weeks fill with Oil? Obviously it is very hard to start...I know that it was full because I took it apart.Installed a new one....Have not started it yet. Looked at all the gaskets and diaphragm are not ripped or cracked...Any Ideas?

The oil pump sends oil to fuel pump and mixes it then send it to the carb bowls premixed. Not like my other oil injected sleds I recently learned this after summer. I'm told the oil pumps on these sleds goes to full open when they fail...Maybe you have a bad oil pump. Just a guess hope this helps.
