High HP Fuel Systems - Q&A (4th Gen)
#61
I'm getting ready to upgrade all my lines and parallel the rails. Was thinking of taking pics of everything along with a list of the parts. Was going to post it as sticky potential. I started this week. Should be done in a week or 2. It will be a complete write up.

i'm in the process of redoing mine as well, got another factory tank to work with, drained it flushed it with water and its drying out now. i ordered an 80 amp relay, 30 amp maxi fuse and 10 gauge wiring off darvex.com and plan to order one of those competition engineering sumps from summit to weld onto the bottom of the tank. i believe they tell you to plug 5 1 1/2" holes into the tank and weld the sump underneath creating a baffle. return will probably be on the front top corner of the tank and i'm still looking into where to mount my A1000 and which way everythings going to run. once i figure out where things will be i can determine which fittings, extra line i may have to order and place the order for fittings, hose and sump.

i also had a question on my own sticky regarding the Return line in my system i had decided to go with the stock fuel FEED line as my Return line to my big boy fuel system i flipped the fuel filter around so that the flow goes the other way, would there be a problem with me running a filter on the return back to the tank the way i have it run?i mean the car turns on and runs but i havent driven it like that i wanted to know if i was going to encounter any problems.

I don't think it matters if you run a filter on the return, but I'm sure it's not needed. As long as you have one on the feed line, the fuel shouldn't get dirty and need filtering on the way back to the tank. I guess it couldn't hurt unless it gets clogged and starts effecting fuel pressure, but I don't see that happening.

I don't know if anyone answered your question yet, but when I had one of the Aeromotive regulators that was hanging off the fuel rail, it didn't hold pressure after the engine was off, so I called them and they said that it was intentional to get the flow rate that they wanted. I don't think it matters, though. My car always started right away, cold or hot with that regulator on there. It wasnt like the lines all drained back to the tank or anything. So when the pump was turned on, it pressurized right away and the engine fired.

Pics of the recent addition. I logged the fuel pressure dropping during every run at the track, after 15# boost, the fuel pressure started to drop with the single Aeromotive A1000. I am triggering the second pump with a 10# pressure switch off the intake. This was also causing the 95# injectors to pull a 102%DC at 23# boost. Now just some final tuning at the track, then off to the dyno for some #s
The dual feed off the sump...
The main pump...
The secondary pump...
The filter and Y setup...
All the factory heat shields fit, panhard bar brace, and the 4" mufflex exhaust. I just went out and logged a quick run, no fuel pressure drop.
