Did the fuel fittings change at all when I Harley switched from MM fuel injection to Delphi? Do I need to buy a different tester for the MM or will one for the later delphi's work?

any ideas on how to do this at home without spending an arm and a leg could be appreciated

 

remove the allen plug from the bottom of the stock MM fitting, install an andapter to fit your fuel pressure guage, ps, its pipe thread into the fitting. then test as usual and compare specs to the book.

ps, just had to recently do this myself, so i know that it works.

 

Thanks Marco, I'll check that out.

BTW, have just started logging data and playing with timing. Will have more to say on that soon.

 

well did you do it?

I checked my bike and see no allen plug to remove. Where is it?

 

Where the elbo threads into tank it will be under it .points down so it's hard to see.

 

Thanks XC, I'll check it out.
