This posting starts off with the picture above for several reasons.
- First, and most relevant to this site, is that the picture represents 2109 (on left) out for a reliable and spirited weekend morning ride, after being down for the previous 4 weekends, until a malfunction was corrected.
- Secondly, it is pictured next to my friend Mike in his DeLorean, which he recently got back on the road, and it is the first time both our cars were out for a drive together.
- Lastly, the picture was taken from my son’s (who was down for Thanksgiving) ’85 Supra, which is a cool car itself, and it represented the 3rd car of that weekend’s impromptu 80’s car cruise.
- Fuel pump
- Fuel pump connector (previously identified as a “connector of interest”)
- Grounds for fuel pump.
- Fuel pump connections at washer bottle.
- Inertia switch & wiring
- Fuse box area
- Ballast connectors
- Ignition Coil
- Ballast resistor & wiring
- Distributor cap & rotor
As expected from a car that at this writing is 28 years old, at each step above, something suspect was found, and then was corrected. In this posting I will only cover a few of the items above, and discuss and show what upkeep was done to those areas, which you may wish to consider for your car as well.
The picture above, was when I first opened the access door about 20 months ago. This was uncharted area for me, since then except for the tank nearly everything there has been replaced today.
- Replaced the original fuel sender for an updated one, then wound up putting the original back on (a story for another day)
- Changed the fuel boot cover (discussed below).
- Changed those orange fuel lines which were beginning to get brittle where they met the hard lines. This was producing a gasoline smell when the car was in the garage, so I took care of that promptly, and it did solve the fuel odor issue. For the replacement lines, I used new fuel hoses rated for high pressures.
- Covered the AC hoses nearby with some pipe insulation to prevent them from rubbing on the access panel.
106684, Upper Fuel Pump Boot
DeLorean Motor Center, CA.
Referencing the service manuals and online parts catalog, my baffle was missing one set of hold down wires, and the bottom circular part.
That bottom part is important, because in effect instead of the baffle forming a drain cup to collect returning gasoline, without the bottom it was more of an in-place open collar. I suppose under low fuel conditions, this would cause fuel starvation, and especially with low fuel at an incline. On this topic, Dave Swingle from DMC-MW stated on DMCTalk, most of the early VIN cars did not have the bottom of the baffle installed, as he has observed in servicing them. I suppose that it is possible that the part was not available for early production, and the factory decided to proceed builds without them. Contact your nearest DMC franchise for availability, should you also be missing one.
The baffle system was reconstructed with the new bottom, and the existing hoses were re-used as they were in good condition. Evaluate your car's hose, you don't want this hose, which it has been known to, kink inside the tank. Also important note: I made the mistake of thinking I could buy regular fuel hose, but that is not recommended as this hose will be submerged in fuel and most parts store fuel hoses are not. Again, if you need ot replace, this is an available DMC part (#106286, $19.69 - not a NOS part).
SpecialTAuto has new Bosch fuel pumps ($134.95)
...and a new higher flowrate pump (#$89.95):
I like the fact that this one comes with those protective boots, for the electrical connections.
Putting it back in is a little tricky the first time and definitely requires some trial and error. The trick is to have it drop in the correct orientation, where:
- the return line inside the tank will not kink,
- where the fuel pump connectors are close to the mating harness connector,
- that the return line does not stick up too much,
- and that the supply and return lines are oriented just right so that their matching hoses line up correctly.
So, reviewing this posting I should note that (if you didn't know) there is a completely new Fuel Pump solution by DMCH. It is a very modern fuel pump that integrates the fuel sender as well. All information today points to a great new product.
