Hi, If I use the Carter M3561 . I do not see the vacuum top portion on this pump. The stock fuel pump has a top section which runs vacuum. If I find a fuel pump with out vacuum, will this create a problem? I know portion of vacuum is for windshield wipers but, I see a line go back to distributor and into intake. If there are any ports which can be blanked off and still function engine, I am interested to.
Thank you for any information anyone has. Note: there is also a 24v pump out there on eBay.
