Not to take away from the original thread but jw what the limit would be on the 3/8” feed? I’ve got a turbo’d 308 that should be making around 500hp and 580tq after finishing tune. Would that suffice? Thanks in advance.

It is my understanding that without a bigger return a bigger feed means nothing because of the return line limits. Leave the lines alone unless you can see some issue like rust or crimping etc. I would run a piece of appropiatly rated hose from the fuel return inlet in order to submerge the flow ala the Pro-M hanger.

I still want those wheels ;)

My plan is to modify the hanger to submerge the return. I figure a piece fuel line hose and a good clamp should do the trick. I had thought about using my bubble flare tool to flare the end for some insurance that the extension wouldn't slip off over time.

I've heard the same that the size of the return can limit the feed. From what I've read the 255 pump is the max you want to use with factory lines after that you will need a bigger return and feed line. I do know these lines a 255 pump and 30lb injectors should be plenty to feed a NA 347 people do it all the time. I wouldn't mess with it if it wasn't for the fact that either when I pulled the transmission or put it back in I damaged the feed line. I have a feeling it was when I was trying to put the transmission on the jack to install it.

We should talk about the rims I'm ready to get rid of them. I just need to get the old tires removed. Now that the fenders are cut and I have tires for the new rims I don't need the old rims to move the car around.
Yep to all of that, we must be reading the same posts lol. If you want PM me about the wheels, my car is still down so I'm in no rush.

This has reminded me that I really need to document my little refresh that is going on...

Don’t get down my friend, you’ve come a long way and I’m not sure if you saw his thread but you’ve inspired a young petrol head to document his build, it’s the 1993 Cobra Clone thread. You’ll hear it run soon.

Cheers Peter!

PS I love that wheel you have there

That’s a good idea ^

What is the condition of your upper arms? I had a set of factory ones in there once upon a time that made a very similar noise, I assumed it was the driveline angle getting out of whack. Ended up pulling them and installing TQ arm (enabled me to set the angle) and no more noise.
