i ordered the regular 255 walbro pump- should i have ordered the hp version. the engine is a 388 with an lt1 intake, tpi computer, 30lb injectors, cc306 cam, 113 heads that have been extremely worked over, around 11.5:1 compression. did a search- but didnt really find a clear answer

 

The regular pressure one is fine for what you're doing, making ~45psi or less is well within that pump's specs.

 

good deal- thanks for the reply. i was thinking that pump i ordered would be fine- thats what the guy on the phone told me he thought would work- but when i searched on here- i was reading all this gibberish about how it seemed everyone was using the high pressure version. i guess- since it's a return line system- it would hurt anything if i would have gotten the high pressure pump. good to know that i can put that puppy in tonight, get the new rear end installed and put the bed back on.....aaahhhh......i mean the hatch (in my best homer voice: doh!they are supposed to think you have a third gen)


thanks
