Low pressure pump and fuel filter

One of the next jobs we completed was fitting the fuel pump and filter to the bracket behind the differential. We used a few different tools and techniques to GBS because it suited our method of thinking.

Things you may need for this job;

An array of drill bits suitable for drilling holes for the pump and possibly the fuel bolts.
Jubilee clips
Files
A spacer (to mount the fuel filter on)
Spray paint


Firstly we created a new ally bracket from the one that was supplied. The supplied sheet had pre drilled rivnut holes which we believe where used in older versions of the car where the pump and filter where screwed into the rivnuts. We opted to rivet a newly cut piece of ally to the chassis. We measured it up and spaced the rivets accordingly.

Holes for the fuel pump were drilled and it was assembled and mounted on the little rubber bobbins provided in the pack. Remember to use PTFE tape on the ends of the pump before you screw on the brass fittings, this will prevent any leaks.

For the fuel filter a small spacer was constructed to make it sit level with the pump. We didn't want it to sit on the ally because it meant putting a bend in the pipe and although this bend may not have restricted fuel flow the arrangement of the two components on different levels looked tacky.

The spacer was constructed from a piece of old oak. I found a large piece of this oak and cut a small section off to make into the spacer. It was then given 3 coats of black spray paint before being glued with the black poly sealant to the ally. Once glued holes were drilled through the top of the wood and through the ally to thread blots through, securing the adjustable plastic tie wraps around the filter.

Finally A piece of fuel pipe was cut to length and jubilee clipped around both ends of the two components.
