A TBI pump won't supply sufficient pressure for an LS1 engine. You could put a different pump in the pick-up unit and use it that way, though.

Re: Fuel pump and sending unit Question
The sending unit sure. Would have to work with your fuel gauge. But you will need a stronger fuel pump. I would suggest a phone call to either Holley or Barry Grant.

What fuel lines do you have? If LS1, the answer is "no".

They can be adapted to fit the 3rd gen pick-up lines, though.

The Walbro 255 pump is pretty popular among members.

Re: Fuel pump and sending unit Question
Yeah, I was going to recommend the same thing - just find a "stock replacement" type fuel pump that'll flow 255lph, & you should be good to go. But lately I've been reading that Walbro pumps have been dying much more quickly than they should be...

...which is exactly NOT what I wanted to hear, since that's how I've taken care of fuel delivery with my car...

Can anyone confirm/deny??
