passinthrgh Posted January 22, 2008 Share Posted January 22, 2008 I am about to convert my 280 from FI to 4bbl and was wondering if I can use my stock pump with a pressure regulator or do I have to use a low pressure pump from a 240? Appreciate any help. Quote Link to comment Share on other sites More sharing options...
Administrators RTz Posted January 22, 2008 Administrators Share Posted January 22, 2008 The simple answer to your question is yes, you can regulate the stock EFI pump down. BUT, the stock pump is built to recirculate... if you allow it to dead-head, it wont survive. Those common non-recirculating carb regulators are a no-no in this case.
