It would, but right now I don't have the time or all the cash to do that. That would requrie me to drop the tank and braze a sump into the gas tank. And then run stainless steel braided lines all the way to the eng. bay. So this is going to be a temporary solution and next year im going to do the sump. The first race of the seazon is on Feb. 26 and my car is a dally driver and everything that I do, requires me to get it done in two days or less, that way I can get to work and back.

I was contemplating the question of whether you could turn the fuel drain plug into a sump and get around doing all that welding and ----. Haven't seen anything about it before.

Also, with this setup, how are the flow rates keeping up with each other? I don't know what your fuel pumps flow, but have you figured out about how much gas will be going where, and how fast? With all these different things in the system, I would think it could be pretty easy to have one pump outflow the other or ones working way hard and doesn't need to or something.

Well it's sitting where the battery used to be. Batteries are filled with poisonous acid that can eat the skin off your body. I don't see the difference.

well.. i figured baterries are made of hard plastic or whatever.. they can take stretching and what not.. but an aluminum welded tank.. i dont think those welds can take much abuse

my over flow tank in my car.. if u look where the mounting bracket hits the tabs.. the plastic is faded and turned white from all the stress off the cars driving.. and turns and what not..

i dont think the engine bay would be a safe place for the tank

i wasnt paying attention to what those returns were but still a failed weld is a failed weld.. and weather it be gas fumes.. or just gas.. thats scary.. run it with water before you pump gas.

i also thought of that.. what if the fuel tank pump wasnt pushing enough and the surge tank tank was working too hard? im sure that would fry the surge tank pump too many factors involved

why dont you just use a plastic tank? thats a hell of alot of a safer bet than steel.. do fuel cells made like that break? but then again i dont think fuel cells are put under the hood.. and stress under the hood of a car is alot higher... like when i put a baterry in the middle of my car and pulled a hard turn.. the baterry didnt move..

but if i had a baterry in the back of my car.. or under the hood not tied down.. that thing flies..

also.. engine bays are hot.. and that aluminum will prolly cause a build up of gas fumes.. even tho they go to the gas tank.. where does that build up all go? my 87 civic wagon.. everytime i pulled the gas cap off it would go pssssssssshhhh like ur opening a pepsi.. wouldnt that surge tank cause a dangerous fumes build up?

im more worried about this than you are :P

It would not concern be to have the tank there.Minor vibrations etc are not going to break the welds.Looks like good by the way nice work.Are you hoping to dig deeper in the tens this year?Any other major changes you have made?

jinxy

its not going to break or blow the car up.....

The only problem I see with using the drain plug as a feed would be dirt and water that goes down to the bottom of the tank.

And as for the pupms keeping up with each other, well I figured that the Walbro 255 was doing ok with being the only one in the system, so it should have no problem keeping the surge tank full. And the Aeromotive pump will only put out constant flow to the injectors and the FPR will route back any unused fuel to the surge tank that will also help keep it full at all times.

The only time I will have to make sure that its full, is when I first install it. And then all I have to do is prime the system a few times and that should take care of it.

As for some of the safety issues that some of you have showed concern, I think it will be ok with having the tank in place of the battery. Most of the surge tanks usually sit right above the fuel tank inside the car. So by not having it there I think that is even safer.

And if you think about it, all the race cars that I know, have their fuel cell in the engine bay next to the front tire.

Yes, but how would a welded on sump be any different? That's why I thought of the drain plug.

Arent the fittings from the sump, usually about 1/2" or so off the bottom ? That way it won't suck out all the dirt and water ?

i thought they were on the very bottom. Doesnt really matter though, that is what your fuel filter is for
