New Era has a killer price on Walbro pumps. I'm thinking about getting one to replace my OEM unit. I'm pretty much stock, & will be bolt ons at the most in the near future. NEPP web site shows a lo press & a hi press pump for my year car. How do I know which one I need? Did a search couldnt find anything relevant to this ?
TIA,
Ian

 

Low pressure is fine for naturally aspirated setups. Go with high pressure if a blower or nitrous is in your future.

 

thanks Josh. Any downside to using the Hi press pump on a N/A engine? I assume the fuel pressure regulator will handle it for me? Just in case I do go wild later....

 

Not really. Technically the higher pressure pump probably heats up the fuel a little more. I wouldn't think twice. Get the high pressure pump for when you get the urge for more power. And you will. We ALL do!

 

roger that! thanks Josh. I got the desire to go fast, now if only I had the $$!
