V8 and L6 Sending units

[2bits]

I see that there are two different parts for the original gas tank sending units. I put a 250 L6 in my truck that originally came with a 307 V8. I am wondering what the difference is. I am wondering if this could contribute to a high fuel pressure. I wouldn't think so, as that should be regulated by the fuel pump, but I was still wondering why they were different. I can guess all the guesses, does anyone know? Thanks.

I think the v8 one has a bigger fuel line. Chris

Yeah, I saw the post that one was 3/8 and one was 5/16, I guess to accomodate more fuel flow for a 4bbl. Just hoping it wouldn't cause a possibility of allowing to much fuel to come down the pipeline. Going to install a fuel pressure gauge tonight.
