What do you mean by "relaxed"? Did you mean replace?
The two stock fuse sizes in the car are 8 and 16 amp. Most aftermarket pumps should be fine for no more than about 10-12 amps.....but a lot of this depends on what else is on the circuit. I would put a stock 16 or similar on it.
Which pump did you buy?

I bought the Delphi one. On the fuel pump it says it requires a 20 amp fuse but I don’t know of any. I’m just gonna put a 16 amp fuse in replace of the 8. I repaced everything so once I wore it in I’m going to fire it up and see what happens. |

| Its common that they list maximum amperage pull at maximum pressure. Most cars using that pump use upwards of 42 psi. You will be drawing less amps at 28psi....so betting you will be fine. Ray |
