Just a question for those that have an efi system. What did you do about a fuel tank baffle?
I had a tank built for me by Boyd Welding in Florida. My stock underseat tank has no baffle unless there was one from the factory, which I doubt. The system doesn't much like washboard roads so I have been looking at a hydromat for that tank to stop the cavitation.
I have my factory rear tank so not sure what to do about this.
Mike - the system we just put on Brandon's uses the Command Module - the only thing he added was a return from the Module to the original tank and a venting gas cap. It uses the same low pressure pump to fill the module - he had an electric he was using prior, but no reason a mechanical couldn't do the job. The only high pressure is from the pump in the Module to the throttle body. He has a plastic tank with a pickup tube in the top. He plans to go to a rear tank in the future, and I'm sure I'll address any issues then with him.
I put a small baffle system in my custom tank when I built it, and will probably do the same with the next one and add a drain plug. Frankly, my system uses a pickup tube to the bottom of the tank and the pump is on the frame rails. Never had an issue and I don't think the baffle system is the main reason - I don't let it get too low, but was more worried about off camber than wash boards.
BTW I confirmed with Holley. The Sniper EFI BBD for Jeep CJ runs the same software as the rest, so it can be bolted to a 4 cyl.
Do you guys know if the carb bolt pattern for the 1BBLs in the 70s were the same as the YF?
