High Flow Fuel Set Up

This is an install replacing the Fuel Pump with a Walbro 255hp and also making a 6-an connection on the fuel bracket for those of us running 6-an SS line.


I actually broke my fuel line while trying to install my Walbro 255 hp then Gary Burch from HYBRID CONNECTIONS gave me the how to on the fuel bracket.

Here is where i broke my line.

Grab some sand paper and sand down as much rust as you can and smooth the top off. also go slowly and keep making the hole big enough for your 90 degree bulkhead connector to fit through with ease.

step 2.
Grab your bulkhead connector and put 1 nylon washer on ( i bought a rubber gasket washer too for extra safety).
Slide bulkhead connector into the fuel bracket and secure it down with the nylon washer and nut.

Make sure that you line up the bulk head connector the same way your stock line was.

I noticed that when I installed the walbro into the bracket I had a gap in the back being that the walbro is smaller. I grabbed the stock fuel line that I drilled out and placed it behind the pump to line it up with barb. Also I replaced the zip ties that you see here with metal worm clamps after being told that the zip ties will become brittle after a while.

Step 4.

reconnect the positive and negative wires to the pump and back on the bracket where the stock pump wires were. Install back into the tank and connect your 6-an ss line.
