Hi guys I’m new here looking for a bit of advice,I’ve had a old td 42 engine out of a scrap car some 15 years now,rebuilt it had the inline injection pump rebuilt to,now I’m putting this in a 64 ford f100 & plumbing up the fuel system I’ve come to a stop looking at the top of the pump from the front of the engine you have fuel in ,then at the rear there’s 2 more pipped unions the rear one I think goes onto the throttle body I think,then there’s one next to the last one ,can anybody tell me where this should be connected to? Thanks
