You can extremely cause a cheap universal external pump, but you'll need to manufacture a custom fuel pickup to sit in place of your stock fuel pump. You'll also need the throttle cable bracket for the manifold.
Electronics
Purpose
Carry on of the generation, both carbs and electronic fuel injection (EFI) effect the corresponding belongings: govern air and fuel into the engine. EFI allows the fuel course to tailor to elsewhere conditions, such as temperature and coercion, also as internal conditions, liking coolant temperature and the air/fuel ratio. A carb can't create any of those matters nevertheless can flow the engine under most conditions aloof too.
Parts
The most distinct matters you'll committal are a inexperienced intake and carburettor, however you'll also need to pay for a distributor designed for non-fuel-injected (1985 and earlier) Three hundred two Mustangs and a throttle kickdown cable. The EFI fuel pump won't grind with the carb; the simplest impression is to obtain an aftermarket drop-in, low strength pump (6 to Seven psi) for approximately $100.
This is a group extended complicated than it needs to be.Technology is brilliant, however calescent rodders stretched ago realized that there can be also yet of a beneficial configuration where electronics are concerned. Although fuel injection helps the machine escape improved in any driving conditions, it can too be reformed an incredibly expensive nightmare in a modified engine.Obviously, you won't be using the stock electronics or computer, so trace the wiring harness back to the inside of the car and ditch it. Or don't: the scrap value of all that copper might be enough to buy you a couple of value meals at your local drive-through. The only things you'll need to keep are the oil pressure sender/harness, temperature sender/harness, tachometer feed, ignition and main power wire to keep the dashboard working. If you've got the extra $200 sitting around, then you can simplify the installation even more by putting in some aftermarket gauges to eliminate all of the original interfaces. A manual with a wiring diagram (like those sold by Chilton and Haynes) will come in handy here.
Cost
Brand new, you can expect to Stare at about $200 for a manifold, $350 for a carb, $200 for a distributor, $100 for a fuel pump, $30 for a kickdown cable and another $200 in miscellaneous for a grand total of about $1,100. For used parts, expect to pay about $100 for a manifold, $150 for a carb, $50 for an external pump, $50 for a distributor, $30 for the kickdown and the same $200 in miscellaneous for $600. That's a bargain when you consider that just reprogramming the stock computer can run upwards of $500.
Considerations
If you're savvy enough to perform this swap, then odds are you're already familiar with the quirks of a carbureted vehicle. It's going to begin hard, idle like garbage when it's cold, require hours of jet and valve swapping to fine-tune the air/fuel ratio and will need a certain appreciation for personality in an engine. However, running a carb will allow you to run whatever pistons, heads and cam you desire, permit easy tuning with basic hand tools and will simplify diagnosis when something inevitably goes wrong.
