Hello everyone, I've been on here before, asking all sorts of questions you have all given me generous answers to. I got a new sending unit for my stock 89 RS' tank, and i installed it and now finally have my 5.3 LM7 in the car. Got new rubber lines and new AN fittings on the fuel lines on the truck injection. I'm running my lines and hanging them up, but which of these gas lines on the stock sending unit is what? I know there is a feed and return, and vent, is the 4th for the fuel filter? If someone could edit my photo or point it out to me "for dummies" i would appreciate it. The car is almost done and i cannot wait to share it with you all on here!

EDIT: I was also told i need a "corvette fuel filter and regulator" from a friend, but someone on this forum said NOT to because i am using the STOCK return style truck intake. I i have is the stock in line fuel filter. Am i doing that right?. Do i need an aftermarket regulator?

 

First question, what pump are you using with the stock sender?

 

You feed or fuel out line goes to the filter , the one you're not thinking of is the charcoal can.

From the left on your photo. Vent, charcoal canister, return, delivery. Also, I think the delivery line needs an O ring. Am I correct on that?

 

THANK YOU, NO BODY could tell me them from left to right, and yes if im not mistaking the delivery gets an o-ring. Thank you again!
