What all is needed for 4.8/5.3 return style fuel system in a 88-95 obs Chevy I don't mind if its a little extra work, but I'm having to pinch pennies here, as I only have 80-90% of the funds as it is depending on the price I can find my motor at. any and all help is appreciated. Thank you guys.
Edit: made some typos, want to run return style system and not the vett filter.
The TBI motor already has a return line, so would these two fittings all I need besides a pump
Rus-644110 and rus-644120

I'm sorry, I meant use the return line. Not return less. I don't want to go with the vett filter.
It seems a cheaper rout to only buy two fittings and use the stock filter and lines.
Editing first post.
Think I found what is was looking for. And for any one els have the same question, here's a link

If you don't use the corvette filter you will need a regulator to get the proper psi.

I'm the guy who made the diagram, don't know why the hell the guy though it was 98 only :lolup:
I was under the impression that the corvett filter held a regulated pressure of 58, and the stock fuel rails regulat that down to a lower 5x psi.
