Ethan's EFI Conversion Tech Day
The next tech day is tentatively scheduled for December 28th. We can do any extra work on December 29th or January 4th, if people are around.
We’re currently hoping to get Micahel and Tomas along with myself and Ethan (I’m not committing anyone, but so far we’re looking good). The loose plan is to meet at Ethan’s at, say, 9 AM, then drive the 25 minutes on I95 to my place in Sharon, MA. This will be the first time Ethan has taken his car on the highway, and we want to be sure that if anything goes wrong, we’re there to fix it or call the tow truck to bring it the rest of the way.
For more things that Ethan’s DMC needs, see this page.
But first, we need to order some parts:
Fuel Lines, Fittings, and Pressure Regulator.
Michael is going to look at ordering these parts.
These are the exact quantities I think we need. Ideally, we should order some extras. I’ve added a “+x” for those cases, like “2x+1” to say “we need two, plus one spare”. I just don’t want to find out we’re missing a key part and can’t actually do the project.
I’ve provided links to JEGS because that’s what I already had from when I did my conversion.
25’ of AN6 fuel line. I used this on my car: JEGS 555-100911
2x+2 AN6 male connector for fuel line, JEGS 555-100091, $13 each
6x+2 AN6 female connector for fuel line, JEGS 555-100001, $6 each
2x AN6 to 14mm x 1.5 Male to fuel filter bottom, and feed hardline, JEGS 799-670520, $8 each
AN6 to 12mm x 1.5 Male, to fuel filter top, JEGS 799-670510, $4 each
2x AN6 90-degree adaptor for fuel filter, JEGS 555-100021, $20 each
AN6 to AN5 union reducer, return hardline to fuel regulator return outlet, JEGS 361-991907. Listed as discontinued, but Amazon sells a two pack for $10: https://www.jegs.com/i/Russell/799/670520/10002/-1
AN6 Male to 16mm x 1.5 Male, to feed hardline, JEGS 799-670530, $8 each
Except the fuel line, this comes out to about $170. I estimate the 25’ of fuel line to be in the $150 range.
Pressure Regulator
This one’s up to Micahel, if he can find something better. Amazon sells a simple regulator that looks exactly like the one Tomas has. It also includes various plugs and connectors. I can’t speak to the quality of them, so I tihnk we should still get all the fittings above anyway.
Fuel pressure regulator https://amzn.to/4hPhGur, $40
6AN ORB to AN6 for regulator. Probably don’t need this if we get the Amazon kit above, since it seems to come with the plugs/connectors.
6AN ORB plug to block second regulator input. Also probably don’t need this with the Amazon kit.
Vacuum Hose
We can just get this from Amazon, but if Michael is already ordering some, that works too.
The lengths I chose are arbitrary; we don’t need much.
3/16” Vacuum hose, 3’
3/8” Vacuum hose, 3’
DeLorean-Specific Parts
For Ethan, we need these parts from DeLorean. The prices are about the same as from DeLoreanGo, but it’s a bit easier to provide links to DeLorean.
The first three (fuel filter, clamp and coolant tank) are required. The LED lights are optional, but recommended.
Fuel filter: https://store.delorean.com/100523-fuel-filter-w-pad.html, $17.58
Fuel filter clamp: https://store.delorean.com/100849-fuel-filter-clamp.html, $3.27
Coolant tank: https://store.delorean.com/101944a-coolant-overflow-tank-stainless.html, $139
LED door lights: https://store.delorean.com/k111532-led-light-kit-doors-only.html, $9.98
LED tail lights/marker lights with updated flasher module: https://store.delorean.com/k111533-exterior-led-light-kit-w-o-taillight-circuit-boards-or-flasher-relay.html, $61
Also, if you could grab something for me while you’re there:
License plate light assembly: https://store.delorean.com/100438-license-plate-light-assy.html, $8.36
Optional
Tail light harness (black bulkhead connector) https://store.delorean.com/101992-tail-light-harness.html $423.11 Not sold by DeLoreanGo, so you need to get it from DeLorean Texas (aka store.delorean.com)
Yours works, but they modified the wiring for some reason and added that bus to the rear right of the engine compartment. A stock harness would replace this, but it’s kind of expensive. We can just remove the bus and solder the wires together instead, or leave it as-is.Engine Cover LIft Piston Mounts. Parts 10 through 14 on this page. https://store.delorean.com/parts/frame-body/8-4-3-louvre-sunshade.html. Be sure to note the quantities.

Air Cleaner
Ethan, this is the air cleaner that Tomas uses, which should fit under the engine cover (should you decide to get one).
Low-profile air cleaner, $35, ebay, https://www.ebay.com/itm/125905563107
Exhaust System
These are for Ethan to get from Amazon:
Borla Pro XS 2.5” dual in/out muffler, $229 https://amzn.to/3Cu8489
2x 2.5” 3-bolt flange, $11.88 each https://amzn.to/3Zbv058 (be sure to order two)
2.5” exhaust clamps, 4 pack, $28.69 for four https://amzn.to/3O9kWDk
2x Exhaust tips. I have these https://amzn.to/3Oao167. You can get anything you like that has a 2.5” ID (inner diameter), but remember that we have some space constraints, and they you don’t want it sticking too far out the back of the car: https://amzn.to/4fRwhnq
From JEGS
Because I can’t find any on Amazon.
5x 2.5” 90 degree bend exhaust pipes, $53.99 each https://www.jegs.com/i/Vibrant-Performance/231/13040/10002/-1 Be sure to get 5 (we need 4, but we should have a spare in case I cut wrong).
From CarChemistry
Exhaust silencers. These fit inside the exhaust pipes and interrupt the flow to reduce noise. I have four of them in my car. You need to order them directly from CarChemistry. I recommend:
2x 2.5” 2-disc inserts, $59.95 each. We’ll have to cut these down to fit in the pipe from the header to the muffler. https://www.carchemistry.com/2-disk-insert-2-1-2-diameter/
2x 2.5” 4-disc inserts, $78.95 each. https://www.carchemistry.com/silencer-insert/
For the options:
- Coated: Painting
- Size: 2 1/2”
To give you an idea of how effective the silencers are, the 4-disc ones claim a 10 dB reduction in noise, and every 10 dB halves the noise level. We probably shouldn’t expect it to be that extreme, but anything will still be better than what you have now.
We can also stuff them with stainless steel wool to reduce the noise further. I only did this on two of my sliencers, not all four; we could try the same thing on your car.
Total price is about $830, not including shipping and tax.
