Little by little buying parts to install at one time. Just got the uppipes. Doing the frx. I want to replace any fuel lines on top of motor. Since I'm doing the frx, what other fuel lines will I need? Thanks

 

I would replace the passengers side. They tend to leak at the most inopportune times.

If you are disconnecting fuel lines, make sure you replace the Parker Sleeves, too! These are the parts that seal the nut and fitting at the end of each fuel line connection.

Dieselorings and RiffRaffDiesel sell them

If the lines are off, probably should rebuild your fuel filter bowl, too. Get the better orings (same sources as above).

This will keep your drain from leaking and air or other problems with your fuel form the bowl/lines.

Also- make sure the drain line has a piece of tubing that allows fuel to run down below the motor and dump to the ground instead of into the valley.

Many of us gut the center post in the fuel bowl to remove the check valve. Unless you try to run without a filter or turn the key on with the lid off the fuel bowl, you'll never miss it!

 

thanks for all that

 

Sure thing. I've asked the same questions- and more!

When your fuel bowl is out would be a good time to install a 90* adapter and a fuel pressure sensor to your output side of the bowl. MUCH easier when it's out!

RiffRaff has those, too. Just a few dollars for the adapter.

 

The regulator on the frx is a tight squeeze just a heads up!
