240+T walbro in tank pump install

[Jressman]

Should I wire this Walbro 450 like the OEM pump and ground it to the assembly and solder the power wire to where the factory wire goes under the stock plug, or just run all new wiring up and out the top?

Using maxxecu instead of factory ECU

The factory wiring will not support a Walbro 450. It needs a large gauge dedicated power wire and relay. I ground mine in the trunk using the OEM spot. It was all done with 12 or 14ga wire.

Thank you!

I was able to get the pump physically in the assembly. I had to cut 1.25” off the hard pickup line with a dremel. I was able to use the stock rubber flex hose. I cut the bucket for the stock pump and stretched it wide enough to hold the Walbro and secured it with a stainless hose clamp. I’ll run the wire harness out the top and clip the old wire leaning just the fuel level sender wire.

Does anyone have a reference thread to the actual re-wiring that needs done. I know I did mine to delete the inline but am second guessing if it is 100% correct
