Funny, I have a 340 sitting here and I will be installing it in a 74 clonerunner in a week or so (440 big block). I am doing a twin turbo blow thru setup and the pump will be supplying a aeromotive 13204 regulator. I have already bought 1/2 inch nylon braided hose for supply and return, though have read -10an would be best and I may have problems because of my boost referenced fuel pressure. The guys that were having issues were using an aeromotive a1000 pump though and it moves much more fuel than this one, so I have hope it will work out. Kevin from csu recommended -10an lines and the a1000, but I opted for the 340 due to quiter in tank operation mostly,not making over 1000hp, and fuel baffle reasons. I am only shooting for 800hp tops anyway (prob run less anyway) I would have to cut the tank open more to put a fuel baffle in it for a different pump anyway. I was going to go with hard line, I would save money but this project is time consuming so I opted to spend a little more for convienence and save some time, well see soon if that works out though. Since i am using a carb i opted for a summit sum-230130, 40 micron metal screen filter.
Last time I cut a tank open I filled it with water and let it flow a bit. After some cutting the water level dropped due to the grinder cuts, then had a small fireball from the air pocket. If a guy dried out the tank first then filled it with water or inert gas I doubt there would be problems. A sharp hole saw should be less sparky than a cut off wheel.Funny, I thought This product was desinged for existing fuel tanks.
Is there not a larger flowing mechanical pump a guy could use if staying carbed and N/A? An electric pump is more time, expense, and noise, and less reliability. My last car had electric fuel pump problems (holley gear style, siezed, low hours, low pressure carb setup ). Only reason I am going this way is boost referenced fuel pressure. Perhaps guys here know of an mechanical higher flowing option? ( I am just assuming there is an option for that) Is the eddy fuel pump you are running the highest flowing mechanical you can get?
Awsome car by the way, that is a mean small block. Looks quite roomy under the hood! clean install. love the yellow!
