While splitting some firewood to burn tonight I decided to let the bronco idle up and get warm to see if moving the fuel lines away from the header would help.
It does seem to help - I moved both the supply and return up and away from the header and let the motor idle up to 180*. It did backfire on me SOME when I idled it up - even did a small power brake in rev. and forward. It's not 100% cured, but I think I'm on the right track with the fuel lines. No where else do they get near the exhaust, but I noticed something else....
While it was idling I held the supply line (flexible SS line) and you can feel the fuel in it. I noticed it was not a continuous supply - it would have a pause in it - then pressure for maybe 10 sec and then pause for 1 or 2 sec. Is this normal? Maybe I have a fuel pump issue???
