One of the biggest changes we see in the lowrider world when upgrading a car is the transition to a newer motor, namely the LS. Although this is a huge advantage in terms of performance and reliability, it does require other changes to take place in order to facilitate the transformation. Trying to adapt these motors to the original, antiquated fuel system that was designed for a carbureted motor is practically impossible. Therefore, when we installed the fuel-injected LS3 on our ’68 Impala, a newer fuel delivery system was necessary.
After doing our homework, we felt that Aeromotive’s Phantom fuel pump system was just what we needed. Oftentimes when retrofitting a car this way, car owners must have a custom mounting ring welded onto their stock tank in order to fit a modern fuel pump and sending unit and they’re never the correct height anyways. Or if you opt for an external electric fuel pump they end up being noisy and either overkill or not enough for the EFI since they’re picky on fuel pressure. External ones also are susceptible to heating up the fuel and vapor locking so the in-tank pumps like our Phantom unit are quieter and cooler.
The upgrade required the fuel pump setup, fuel filter, fuel regulator, and a supply and return fuel line. Plus we were able to adapt this to our stock fuel tank, which is certainly a cheaper option than welding a sump into your tank, having a custom tank built, or installing a fuel cell that’d take up trunk space. This system is designed to fit virtually any kind of tank and can even work with a carbureted setup if you decide to go that route. Follow along as we show you the steps involved in bringing our Impala up to 21st century performance standards.
1. The location for The Phantom was traced out in the deep end of the stock fuel tank. We also reinstalled the tank into the car to check the marked-out spot for floor clearance.
2. The marked spot was cut open using a hole saw.
3. Utilizing the billet template as a guide, the holes were drilled perfectly for the mounting hardware.
4. Aeromotive supplies a billet template for preparing the spot and checking fitment for the Phantom location.
5. After drilling the holes, the mounting ring was dropped into the tank with the studs pointing outward so the gasket could slide over them. The fuel pump depth of the Phantom is adjustable in height by cutting the bracket so it can fit any size stock tank.
6. Phantom fuel pump system all bolted in and ready to go without any fabrication needed.
7. The fuel pump leader wires were attached to the Phantom while they were accessible outside of the car. As for the stock tank sender unit, it will now only be used for the fuel gauge and the tube will be blocked off. Aeromotive also supplies a strip of foam tape in order to drop the tank down enough for necessary floor clearance.
8. The fuel tank is now reinstalled in the car with the fittings attached for the start of the supply and return lines.
9. Aeromotive’s billet fuel filters have been engineered to provide protection against debris yet allow minimal flow restriction, and they can be disassembled for cleaning when the time comes.
10. Once the fuel lines were mocked up on the car to determine the length needed, the cut location was marked off with masking tape. We then used an abrasive cutoff saw to make the cuts.
11. By cutting through the middle of the tape mark, it keeps the fraying of the stainless strands down to a minimum.
12. After cutting the braided hose the tape was removed and the base of the hose end was carefully pushed onto the freshly cut end. Care should definitely be taken during this process since a frayed end will make it very difficult to install the ends.
13. Before installing the fitting into the base of the hose end we applied anti-seize so it’d slide into the hose and also so the threads wouldn’t gall up with the base during the tightening process since it’s a compression fitting.
14. The Aeromotive fuel system is controlled by the fuel regulator that was mounted on the firewall of the Impala. It allows you to dial in the exact fuel pressure based on your engine application and demands.
Axalta Paint Tip of the Month
By Axalta Coatings Systems
Maintain Your Equipment Maintenance
Whether you are spraying water or solvent base products, this important Axalta paint tip of the month also happens to be a reminder for all you painters out there. When you happen to come across pinholes or micro-pops in the basecoat, or that clearcoat finish looks like it dyes back, this problem may exist because of the improperly scheduled maintenance of your paint equipment. You must make sure your compressor and pre-filters are maintained quarterly. Change out your air hose every three to six months depending on the volume of work involved in the shop. Replace your spray booth filters as needed, and clean your spray guns on a daily basis to ensure a quality finish. These simple maintenance steps should get you the final paint results you are looking to achieve every time! Please remember that it’s all about the pre-maintenance of your equipment, my friends.
