Hey all,

Stockpiling buildup parts and have a quick fuel pump question. Will be running a 331 with HCI and a likely 125 shot. Been surfing ebay and all the pumps I've found are the high pressure units. Any downside to putting that into a non-blown auto? Thanks

your going to want the normal EFI high pressure pump, not a low pressure carb piece, usually you will get an added high pressure pump when installing a SC, boost a pump, or some sort. I'd go with a Walbro 255 lph pump,

I agree.

But it really depends on your setup. Is this a wet or dry kit? Are you running a seperate pump for N2O? If your using a wet kit, then you can probably rejet it to run at any pressure you want.

Great to hear. This is what I have been eyeballing,

but I remember some people saying that the high pressure unit should only be used in boosted applications. No problems then?
