im going to replace my fuel pump to try and track down a problem and im wondering whats the best one to get for a stock motor? thanks.

I also recommend OEM(AC Delco) pumps on these cars as well since I haven't seen a whole lot of pump failures except on pretty high mileage W-bodies.

my OEM fuel pump went out around 200,000 miles IIRC. i bought a Masters brand fuel pump (for a TGP) from Advance for around $100. after reading some of what people say about Masters brand stuff i wouldn't recommend them however. my fuel pump has been fine the past ~40,000 miles but it groans loudly when i'm low on fuel. i'm planning on replacing it with a Walbro fuel pump soon. for a stock motor i'd probably use a Walbro 190 ltr/hr pump. i used a Walbro 255 ltr/hr in my old GTS and will probably use the 255 in my Cutlass as well.

There's a Walbro 255 ltr/hr pump in my Bonneville and my dad's Suburban. lol Both run great.

im slightly confused, there are two walbro 190's a high and low pressure right? and if i get one is there any special wiring i have to do to hook it up or does it plug right in? thanks.

sorry, but it didnt really seem out of place. not a big deal. so anyways does anyone know how it hooks up? thanks.

Are the fuel pumps for a NA 2.8/3.1 and the TGP the same? I heard there was a difference in the wiring :? , Maybe not?

 

Thanks,

Mitch
