Stripes

At the POCI 2022. Our 69 400 convertable represents what Pontiac built, Excitement!

I would recheck it. Its pretty common for the old rubber ring that goes on the filter to get stuck in the transmission and not be noticed, and then when the new is applied you have 2. For the brief time it takes to look, I would. Transmission rebuilds are not cheap.

The line from carb to the pump is pressurized with gasoline. If it leaks, it can spray fuel onto your starter, alternator, plug wire, etc and burn you and your car to the ground. Every car I have ever seen from the factory has metal lines from the carb to pump. If the suction line leaks to the tank, it just quits pumping fuel. So, Frosty is giving some very bad advice based on others that have done it wrong many times. If the line never leaks, it might be ok. Even the NHRA limits the amount of rubber fuel line a car can have and race. This includes steel braided lines. This is for fire safety. Many car fires are caused by leaking rubber hoses. In a claim I investigated, a drunk patron returned to his truck and passed out with his foot on the accelerator while in park. The engine screamed but no one wanted to break a window of another's car. The alternator got hot enough to fail and dripped hot metal directly on the truck owners altered rubber fuel line. The resulting hole sprayed gas directly behind the reved up fan. Igniting and resulting in an inferno that killed the owner and burnt the truck to the ground. Those metal lines are there for a reason. The carb has a place for an internal filter. Use rubber lines in very short sections to connect metal lines together, or for emergencies. Otherwise, spend the 20 bucks to replace the line with steel.

I've never seen one, but I have heard they exist. My bet would be less than 20 cars. It was an optional gear, so very few cars would need it. 355 was pretty common. Lower pretty rare on a stock firebird.

Vapor lock

Good luck! With the vapor lock issues we had, we didn't have a choice. While we are very happy with the Sniper, had we not had carb / vapor locking issues we would still be running a carb. As they add more alcohol each year to the gas, it gets more difficult to keep from boiling fuel in the lines, especially with increased hp which generates more heat.

Running the single gas line to the front really simplified the installation. With the pump in the tank, the regulator returns everything over 60psi directly back to the tank. Pressure line to the front covered in tape.

Wiring the Sniper was easy. The hardest part is removing all the wires you don't need, like nitrous, electric fan. Etc. You first take the car and have the exhaust bung placed in an exhaust pipe. Wires to hook up: power, ground, temp sender, O2 sensor, fuel pump wire to pump. To tune. tell the system the engine size and desired idle and start it. If self tunes. I think driving it around it tuned itself 80% in about 30 minutes. The Xflow Sniper uses a external fuel regulator, I set at 60psi. I bought a replacement battery that was the same size but had top and side post. I hooked the main power off the provided harness to the side terminals so I could continue to use the OE spring ring battery terminals.

Regarding the tripower. Thier advantage is they look cool. A single 4 barrel exceeded there performance when the rodchester was born. The fuel injection is even better.
