Correct Walbo p/n?...Overkill??

OK, I almost totally forgot about an upgraded fuel pump for my 350 swap, but is this what I'm looking for?

Also, yall don't think 255 is too much? I mean, would a smaller and less expensive pump do the job? If I remember correctly, a 255 pump will support like 800 HP.

Thanks.

they make a 190 ltr/hr pump as well and i think that would works better with tbi . i think i read somewhere that it stock fuel pressure regulator can handle it just fine but the 255 requires an aftermarket regulator and ive read that some people have had problems getting the fuel pressure down into tbi range even with the new regulator. When i do my motor swap im going with the 190 , its more then enough unless you plan on goiing to tpi or something liek that in the future. search on the tbi board for the walbo pump .. its been talked about alot.

hope this helps

My 255 floods out my stock regulator at low pressure , like 15 or lower, seems to keep a constant pressure above that though. The 190 would have been plenty for me.

The 190 will be more than enough. Some just like the old saying "if some is good more is better."

Thanks for the link. I went ahead and ordered it. Hopefully it does the trick and I've remembered everything I'll need for this swap.
