Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Equipment Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Is he good with Mopar?

Mechanic's Assistant: Anything else you want the equipment mechanic to know before I connect you?

Mostly fuel system complete on the conversion and can i download the answers for reference after our chat?

Hi ,I'm Wayne.

I'll be assisting you with this issue today.

All you need to do is run a line from ele pump to fuel tank

then outlet line to the primary fuel filter get a pump that is 9.5- 12 lbs no bigger

as far as primer pump, leave as is

to bleed the fuel lines crack the injector lines lose and crank over 10-15

sec intervals, when bubbles are gone tighten the lines and hold the throttle to the floor and start

keep it there until runs smooth

I hope this helps you

Wayne

My goal is to give you the best experience possible.

I hope that I have earned a 5-star rating
