Fuel Installation 1 - In-Lines & Fuel Pump

So, when it comes to fuel pumps, there are two well documented approaches.

 

1. Replacing the in-tank OEM pump with one of the uprated ones

 

2. Install an in-line, engine bay mounted more powerful fuel pump

 

There are pros and cons for both approaches, however the I decided to go for the in-line route as I believe it to be a lot simpler and should there be any failures, it would be easily accessible.

 

After some research, I decided to go for the Bosch 044 series, which seem both powerful and reliable.

 

Wiring

 

The pump will be run directly from the raw feed from the battery and triggered through a relay by immobiliser managed supply.

 

This way, it ensures that the fuel pump gets good feed from the battery and not use original wires that my be too thin to take the load.

I crimped the connectors and fitted a heat shrink tube to keep everything in place and well supported. Those Hondas have some vibrations on them.
