I currently have a pair of Walbros (don't recall which model to be honest) and I think they're at the end of their life.  I need to replace them.  Should I go with 485 or the Hellcat models?

Personally the helcats seem better as they are E85 specific and not universal as the other are

Some tuners advice against using new 525 warlbros in the factory fuel boat, at least not as a primary. The reason given is notably higher current draw and heat dissipation for relatively trivial output increase (something like 10% at GTR operating pressure levels). It was said factory in-tank wiring and harnesses have trouble coping with increased power demand. The recommendation is to run high-pressure “274” model of normal 485 warlbro.

My tuner advised the same when I asked him about these new pumps. I even have large gauge direct wiring straight to the pumps and he still advised against them due to heat concerns.

I heard that too but when I spoke to my tuner (Bill @ SiR) he said otherwise.  Regardless, I'm getting the injectors cleaned today and going to see how a data log looks after that.  If I need to replace pumps then I'll have to do some more homework.

 

How are the AEM pumps?
