While on another project, I checked out #E1ZE-G2A ABE to #F6UA NDA. These are 81 to 95 era 31 pound per hour pumps
The Secondary Air Injection Pump hardware is similar, but the EECIV pumps have TAB/TAD or DPFE electronically controlled.
You can short belt the serpentine system and leave the TAB, TAD,and the EGR hooked up.
All the vee OHV engines with sep belt were same as the historic 4.2/5.0 pump, which use a 4.5" pulley like this
"1979-1993 Ford Mustang 289, 302, 351 Windsor" see

86 was a pivotal year, when Ford changed its time honoured external Thermactor and EGR systems control hadware to incorpate electronic EECIV control.
But generally, all OHV sub 8 ton GVW passenger cars ran the same generic 14.06 kg/hr (31 lb/hr ) pump for years and years to 1995. Pretty much anything the same hard dimensions fits. Ford has an internal Fxx code for ones that swap.
The 2.3 OHV HSC engined Tempo/Tracer were first for 84, but they ran 7.7 kg/hr 17 pound per hour air pumps (Ford Air Pump #E1ZE-D2B for 4 cylinder Escort, EXP, Fairmont, Granada, Mustang, pinto, Mercury, Bobcat, Capri, Cougar, LN-7, Lyn, Zephyr).
Depending on the secondary AIR system, prior to 86, every 1981 to 1985 Ford used versions of the E1TE-9B289-AA "Smog Pump Thermactor Air Bypass Diverter Valve" with a 31 pound per hour air pump on 232-460 (3.8 to 7.5 liter) passenger or sub 8 ton GVW engines.
1981 Ford Mustang 3.3 liter Emissions Air Pump # E1ZE-G2A was 31 lb/hr, but a different design.
" Port in Housing" Cardone 32-291 is the generic type of 1981 to 1987 pump E1TZ-9A486-B Ford Econoline E150 E250 E350 1975-1987, but also fits 5.0 Mustangs till 1992, so it is 31 lb/hr.
370/429 F-Truck stuff 1980- 19 91 to is 31 pound per hour, but of a different design (Nippon Denso/ Ford Motorcraft OEM Air Injection Pump - Smog Air Pump CX1009 E5HZ-9A486-A.
NEW OEM Ford Smog Pump E5TZ-9A486-K Ford F-150 Bronco E-150 5.8 V8 1985-1987 CX1111 but is 17.44 kg/hr 38.4 pound per hour
F53 are generally 85-90 F-Series pumps, but Ford rolled out EFI gradually in stages on the whole in line, bent six/bent egith engines. (Cardone Industries 32-301/32-607/32-623 Remanufactured Air Pump, Post carb era air pump eg 460 EFI)
