Fuel Pump upgrade?

[swami]

hi all,
sometimes my car starts hard unless i turn on the key for a couple of seconds to let the fuel pump prime so i figure i need a new one. when i shut it off i hear a whistling sound in the fuel tank as well. my car is stock except for dynomax catbacks and air silencer removed. would a high output fuel pump improve performance or will the stock replacement suffice? i have no hopup plans at the moment. TIA

A 155 unit will help as some of the ATX got lower flowing SLO units. It may not exactly help with performance but it will make sure yours is up to ***** as the SLO units barely make it.

is there anything wrong with one of the airtex units from rockauto? TIA

I have one in mine and it works.

I would check to see if the ATX one gets one from a SLO or a SHO unit, unless they are all the same. The SLO ones are barely enough.

the 3.0 and 3.8 take different part #s. the 3.0 and 3.2 are the same. i think i will go with the airtex while it is on sale. thanks for the advice.

should i replace the fuel strainer while i'm in there? i know they're only $9 but, i'm not for replacing it if nothing is wrong with it. TIA

Yes, replace the feel strainer that goes onto the pump.
I would also replace the fuel filter.
Some have had bad luck with the Airtex brand. It's a crap shoot.

airtex is an oem supplier to honda and suzuki and they claim 50,000km life expectancy. TIA

id go with the Walbro 155.
should you decided to mod at some point you wont have to mess with the pump again unless boosting alot.

DO NOT BUY AIRTEX PUMPS! THEY ARE A POS!

Carter, Bosch, Delphi, AC Delco, or Motorcraft are all good. I work in auto repair and would never recommend Airtex if you don't have to

These people all speak the truth. I am NOT AN ARTEX FAN!!!
I have had to replace 2 Artex pump's over the past year. The first one lasted 2 weeks!!!

i also got a question on topic, on all mtxs i know of and im sure atx but anyways they have high and low side pump... im assuming this is to help protect the pump from burning up? it will run in the low side till high is needed...

if anyone can verify would be great
