Since the original fuel system on the DeLorean isn’t the best designed system, I decided to upgrade it to the DMC truly modern replacement for the over-complicated and under-performing in-tank fuel system components (Part# 107000).
This new the DMC Fuel Pump/Sender Module replaces all of the mild steel and rubber components in the tank that are prone to deterioration and is a modern replacement with an integrated fuel pump and microprocessor controlled fuel sender for the other original, trouble-prone internal tank components. This new system is ideal for cars that are driven regularly or infrequently, the materials used are said to be supremely resistant to the additives found in petrol. It uses the existing electrical connectors so it is easy to install and comes with fully illustrated instructions to guide you along the way. The individual components are also available and replaceable if ever required!
Both the fuel pump and the fuel level sender are located in the fuel tank and are accessed through the spare tire well in the luggage compartment. There is a panel in the rear of the well that is secured with ten M5 screws. Once the panel is removed, the top of the fuel pump and its associated assembly is easily obtained.
Replacement is reasonably straight forward when following the provided instructions.
I started with removing the large band clamp around the boot. The pump can then be lifted up a few inches to inspect the tank, but to remove it the hoses need to be disconnected from the bottom of the pump and from the return hose tube. A few inches forward is the tank sender. It is secured by a threaded knurled ring. When faced with the necessity of changing the pump and ancillary items, and not changing the tank, there is no advantage in removing the tank itself. Access to the inside of the tank is through the pump mounting hole only, so unless the tank is to be changed, do the repairs with it in the car.
On completion I had difficultly refitting the panel located in the rear of the spare tire well in the luggage compartment that is secured with the ten screws, no matter how I angled the new fuel module, the panel would be held up with the new system installed. After communication with DMC Admin Support, I was advised it is as good as it can be, and it often depends on where the cutout for the panel was made in the underbody in production.
The panel can actually be fitted with a little effort by starting the bottom three screws and then uses a pick to stick through the panel hole and into the underbody hole and guides the rest of the screws in, and then by tightening them all down. It was a very snug fit and rests on the module, but it won’t damage anything.
The new modern-style fuel system upgrade is essential for anyone having fuel delivering issues, just knowing the upgrade has been done is great peace of mind.
