Fuel Systems

This lesson was a continuation of last weeks’ lesson, (see blog entry 3, Fuel Systems), designing the fuel system for the Norma.

This week we started off getting an estimate price for out custom fuel cell at around €1500 or £1076.27.

We then started to browse the demon tweeks website looking for a fuel filter and checking through the products we had already decided on, whilst browsing the site I found a Protec fuel system dual mount kit for our Bosch 044 high pressure pump. This is a system that holds the pumps side by side and they use the same outlet and inlet. Using this mount we can have the pumps out of the tank and we now have our reserve pump (the Bosch 044). The cost of the mount is £145.38 and one more 044 pump at £158.80. With removing the pump from the cell this has increased the capacity of the cell so we will have one more capacity reducing ball of 0.52 size and costing £4.65. All together now we have 79.92L this is good because we are now even closer to the 80L limit and we have a good and accessible pump layout.

The filter we have chosen is a fuel lab high flow inline filter 848xx series which has an integrated check valve at £126.25, there isn’t much to say about the filter other than it is available in multiple colours and the elements are replaceable at around £10 each for a new one. With this system we are aiming for high efficiency and with our design so far all of the components are easy to replace and are accessible for servicing.

To connect the system together we will be using Goodridge 200 series fuel and oil hose at £66.87 for 3m of size -6 braided hose.

For scrutineering to take a fuel sample we will need to install a dry break connector in the system so they can take a fuel sample we are using an ATL quick disconnect staubli coupling this will cost £385.96 and is an essential part of the system because without it the car won’t meet regulations and be able to race.

This is as far as we got in this lesson but we will be carrying this on for in the future for our presentation but we will have no more lessons on this. Below is a picture of my notes from the lesson, there aren’t many because we spent a lot of time searching for components online.
