Aeromotive Stealth Fuel System

At this point I am certain I am overbuilding this car, but at least I am thinking towards the future!

I just ordered a factory appearing stealth fuel system from my local speedshop to replace my failing 40 year old factory setup. I knew I had to update my fuel system and even though a mechanical pump and 3/8" line would probably be plenty for now I still would need a new sending unit, and tank. I have been having intermittent fuel starvation issues since I have owned the car. Sometimes it runs great, others it just about falls on its face past mid throttle. The stealth fuel system is a good deal and will allow me to have room to grow whether I go EFI, forced induction or BBB.

I am sticking with the 800cfm Qjet I had built by Everyday Performance, I feel I can get what I need out of a quadrajet just fine and I don't need to jump on the Holley bandwagon. So in doing that I am deviating slightly from what Aeromotive recommends. Since their setup incorporates an adjustable fuel log fed by -6 line, I am going to go with a single -8 line into the qjet. I haven't decided whether I should use a banjo adapter fitting to convert the Qjet to side inlet or if I should just use a 1" 20 to -8 adapter and just run a 90* off the hose end. Either way I don't think I am going to use the inlet filter. I am running the recommended inline filter after the pump which should be sufficient.

For those that have done this before, what have you found the best inlet pressure to be? I am assuming no more than 7psi. I am spending a lot of money on this setup, so I really hope it works just like described and eliminates the loud fuel pump whine common with pumps like the holley blue.

 

I have most of the parts needed for my fuel system upgrade, just need to pick up some line clamps, new gaskets for the carb and an AN carb inlet. I finished wiring everything last night and I will hang the tank today and possibly start running some line.

So where I am stumped is, what the best way to run my -8 feed and return line? I was thinking of running it on the passenger side of the frame to avoid the steering box and brake lines. I don't see it being possible to follow where the vent line was run as I would be trying to stuff two 1/2" lines into that space. I don't want to kink the line and risk damaging anything or causing a leak in the future. I could use a reinforcing spring but I would like to avoid that. I am using Earls Pro_lite 350 I am starting to wonder if maybe I should use something else... at $200 per 20ft its quite expensive. I could run aluminum line too so I would appreciate any suggestions. I would really rather stick to a line that will be compatible with earls ANO-Tuff (swivel fit) fittings.

Another question, What do you guys use for safety switches? I am using the recommended pump wiring kit so I have a breaker accepting power from the battery, running that to a relay which will be trigger by key on power. I don't have a switch right now just key on power. A rocker switch would be fine but I already have a crowded enough dash area and don't want to chop up anything to run it on the face of the dash. I haven't heard good things about oil pressure safety switches either.

Thanks for any advice.

 

I will probably start at 6psi and adjust from there to see what the car likes best. I shouldn't need much more than that since this is still a stock motor for the time being. Should be a major difference since with my old fuel system I was getting as low as 1psi on some WOT pulls and I still would run low 14s

 

I used teflon stainless braided for my fuel system. -8an to regulator, -10 an return. Teflon lined will last forever but the radius is longer for turns.

 

I ran my half inch return and feed lines between the passenger side frame rail and body. The area was a nice fit. It enters the engine bay inside the passenger fender to the regulator mounted to the front corner of the passenger fender. I haven't had any issues with it so far (~2 years).
