Hey all,

Quick question, I have a stock 85 Firebird with a 2.8 ltr automatic.

I think I may have to replace the fuel pump again but am curious as to whether or not I should use a OEM replacement pump like I did 5 years ago or would I be able to install a high-performance pump without any doing any upgrades to the engine?

Any input would really be helpful.

 

The fuel pressure regulator will control the pressure so using either should be fine. Go ahead and throw a Walbro in there.

 

As a side note though, unless you do some modifications you really don't need an aftermarket unit, though thye might be more reliable

 

Thanks for the input, the biggest reason is because I replaced the fuel pump about 5 years ago with an OEM and only drove the car maybe 2000 miles since then.

I was also thinking a higher performance pump would possibly be more reliable and last longer, plus if I decide to upgrade the engine at a later point I would not have to do a fuel pump changeover then.

My biggest question at this point is should I install a 255 ltr Walbro or a 255 ltr HPF pump. I have heard several cons against Walbro but have seen nothing that actually compares the two units.

Any comments?
