change 993 fuel pump to aftermarket
Can a Porsche 993 fuel pump be changed to an aftermarket fuel pump such an Aeromotive Fuel Pump without any problem ?
I plan to change my fuel pump, because my fuel pump is noisy right now than it used to be and if it is ok i want to change to Aeromotive Fuel Pump.
Any help would be appreciated. Thank you.

Unless the stock pump cannot supply enough fuel, I would just replace it with a std. one, one that doesnt make noise

I totally agree with your suggestion Chris, but the problem is that my fuel pump is noisy right now, and i'm going to check whether the fuel pump supply enough fuel or not next week.
If it is not supply enough fuel, i just plan to replace the fuel pump with a new bigger capacity atermarket one..
The reason i want to buy an aftermarket, because the stock of the aftermarket is available, not like the Porsche Oem that i have to order and wait from other country.
I live in Indonesia that only have 1 porsche centre for the whole country and they don't have the stock for the fuel pump and don't have many 993 parts.
Thanks for your kind help Chris & forgive my bad english.

Or its feed is restricted and that makes a good case to pull the in-tank filter screen and have a look.
Its worth repeating that these Motronic Bosch pumps are axial-flow units that are cooled & lubricated by the very fuel they are pumping. This means that when the tank is very low, air can be sucked in that will make the pump noisy and if the tank is permitted to run dry, these pumps suffer some damage while repriming to start and that shortens their life.
Given the operating pressure, pump volume, proprietary fittings, and durability of these Bosch pumps, I would not use anything else on these cars. Race cars get the Bosch Motorsports version of these pumps (higher volume for 350+ HP).

Seems that i have to agree with most of you to use an OEM pump, Thanks a lot to all, i really appriciate the help, and there is no other choice beside uses an OEM fuel pump at last.

There are some who feel that the new, silver OEM pumps are of dubious quality relative to the old blue pumps and that they may have been outsourced. Does anyone know: Is there any validity to this?

Bosch pumps have been extraordinarily reliable over the years with no real history of troubles.

It sounds like the 044 Bosch can be purchased for $200, which is less than the original fuel pumps, and may be an option.

If you ever plan to upgrade the engine to 450hp you can replace the pump with a Bosch "044" motorsport unit which is a direct replacement provided you make a special fitting for the M18 outlet port of the pump. I run these in all our high hp applications and have yet to have an issue. Otherwise just buy a new OEM Bosch pump with the same fittings and all will be good.

I'm working a potential fuel pump failure on another thread but found this and would like to ask if I should replace the fuel lines as well as the pump?
Having suffered a VW fastback fuel line fire in the past I worry about this. Are the fuel lines the problem or is it the clamps that attach them?
I'm thinking I should replace the whole fuel line as well as the pump?
Am I paranoid?
