Will be replacing a single fuel pump on a 91 Regina system this weekend. Anyone been down this path of looking up pump models on Autozone and Partsamerica to find they list an Airtex/Master E3210 ($50 Autozone) for the 1990 and a E8279 ($90) for a 91 and 92? Airtex web site lists the E3210 as a 65-95 psi dead head with 40gph, then the E8279 is a 80-90 psi dead head and 45-55 gph. Got the original volvo pump 3531165 (really an AC delco) to run in a can of gas and it pumped to 50 but it's old. Car has 182k, must have been changed before. The Fuel pressure regulator does not appear to change from 90-92 so it doesn't look like the higher pressure and flow is really needed. I am planning to buy the E3210 for this 91.

The 91 has the pressure dampener right at the pump. Does the 90 have it too? Any ideas to why the parts places list the higher pressure pump for only 91 and 92? Anyone using a E3210 on a 91 or 92?
I suspect the E8279 will just last longer.

Thanks,
Dan
