Project Cappuccino: Upgrading the Fuel System

  • Dave Zipf
Denso 952-0003 pickup sock vs the old fuel sock
Unfortunately for us, Walbro did not have any of these installation kits in stock when we were installing our pump so we ended up ordering a different kit that gave us the spacers but not the filter sock. The sock AEM provided does not fit under the rubber isolator that secures the bottom of the pump. We instead ordered Denso 952-0003 which is a direct replacement.
New AEM fuel pump and pickup sock installed on the pump hanger
We installed the new filter, o-rings, and spacers onto our new pump. We then reinstalled the isolator and installed the pump into the hanger. If you’re looking for a factory replacement pump in the US, it looks like Mitsubishi used the same pump, mounts, and pickup on the non-turbo 2nd gen (1994-98) Eclipse.
Fuel pump hanger reinstalled with new stainless steel mounting screws
Hanger assembled, we can reinstall the pump into the car. Installation is the opposite of removal. We went ahead and replaced the mounting screws with stainless steel flanged Allen bolts as our old screws put up a fight on the way out and we didn’t want to risk stripping one during reinstallation.

While we have the fuel system depressurized it would be silly not to replace a few other important service items.  We don’t know when the fuel filter in this car was replaced and they are very small and easy to clog.  All of our rubber fuel lines are three decades old.  Dry old fuel lines are a recipe for a fire so let’s go ahead and replace all of them too.  We decided not to change fuel injectors at this time since they are adequate for our current power output and we are not going to a bigger turbo…yet. 

Evil Energy high pressure, ethanol rated fuel line still in box
For the fuel line we picked up some Evil Energy EFI hose. This hose is rated for ethanol fuel: again, selecting parts that are resistant to ethanol will prolong the life of the fuel system. Non ethanol hose can oxidize in a few years and cause fueling issues. This hose is also rated to 300 psi, which is nearly six times what our fuel system operates at, ensuring we should never deal with a dangerous fuel system rupture. Note that Suzuki uses two different sized fuel lines: the feed lines are all 5/16” while the return lines are all ¼”. You will need both sizes to plumb the car or you risk the return lines popping off and dowsing your engine bay with gasoline.

    This is a cool project. Getting all the power back is a huge deal at such low numbers lol. I have really considered picking up an AZ-1. Didn’t you make a comparison article where you decided between the Cappucino, AZ-1, and the Beat?

      Hey James,

      We have not done a full comparison of the ABC cars. I’ve test driven a couple of Beats and ridden in an AZ-1. In our Project intro for the Cappuccino I discussed my reasoning for picking a Cappuccino over a Beat or AZ-1. I think I would quickly summarize them thusly:

      AZ-1: Most expensive of the 3 due to its rarity (about double the price of a Cappuccino). Very cramped. No trunk or frunk. But man are they cool. It really is a mini DeLorean: awesome to look at and you’ll get a ton of questions but not the best day to day car. Also the cabin is a glass bubble so they get very hot in the summer.

      Beat: Usually the cheapest of the three. Super fun to drive, and they’re great with the top down. But slow as hell. Naturally aspirated 660cc engine just has no torque. Great engines once they’re wound up a bit. Great cruiser especially if you live somewhere you can have the roof down all the time. Great interior too. IIRC, the roomiest of the 3. The trunk is pretty small but the interior has lots of storage. Beware of leaky roofs. I’ve heard they’re not too hard or expensive to replace though.

      Cappuccino: Probably the best all rounder. Has a real trunk. Has a decent interior. 3-piece roof is great. Definitely the best for performance and the fastest of the 3 (that’s not saying much though). Lots of aftermarket support even today. I’ve had mine for 7 years now and still love it.

      For any of them there are a few things to keep in mind. Not sure where you’re from, but if you’re in the US, you will need to either be a good DIY mechanic, or line up a shop that is willing to work on your car. A lot of shops won’t work on them. The Cappuccino has an English service manual, not sure if the AZ-1 or Beat do. Make sure you inspect your car thoroughly. DIY maintenance on all of these cars is tough. Everything is small and cramped so you have to get creative working on them. All of these cars have a tendency to rust and sometimes it is not obvious. The cheapest route is the DIY import route but it’s the riskiest. Rust will be hard to spot in the port photos and you won’t be able to drive the car until it’s already yours. I’ve heard a number of horror stories from DIY importing. A car that’s already imported, either by a dealer or privately, saves a lot of time and hassle and you can actually drive and inspect the car you want to buy. Finally, remember that these are hard cars to live with. They’re impractical, hard to maintain, and old. But any of the ABC cars is a blast to drive and people ask about them all the time. I highly recommend getting an ABC kei car, just be prepared for what you’re getting into.

    That fuel pump was plenty for Project S2000 with the turbo added, so you’ll have all the headroom you need for more power 🙂 While the fuel system wasn’t the root cause of your issue, it was good to upgrade everything on a car that old!
