Gas Tank Sump Clearance
I've been meaning to get my tank sumped for a while now but haven't gotten around to it. Anyway I've been wanting a sump with bigger than -8an fittings and neither summit nore jegs carry them, actually I think one of them does but it looks huge and I believe its a circle track sump by aeromotive. Anyway, I found one by wild race cars
WILD RIDES RACE CARS (bottom of that page)
here's a picture
I called and asked him if he knew of any clearance issues with the upper panhard bar on these cars with the sump and he told me he does not know, they mostly do mustang work.
However he did tell me it was 3" tall at the deepest location for 1/2" or 3/4" (which i planned on getting).
So i wanted to know if anybody here has purchased this sump or even if they did not I would like to know what you guys think? Would it fit fine n dandy or would there most likely be contact with the upper bar? Thanks in advance guys.

Here is a picture of mine. It is not as large as the one you are looking at, but it may help. The only clearance issue was with the muffler, which I got rid of.

I made a mock-up sump using the box from a 12 pack of soda pop. Once I had exactly what I wanted, I took the template to a furnace and air duct fabricator. I picked it up the next day and he only charged me 12 dollars! I had to install the pipe fittings myself though. I used a 1/2" female pipe coupler and cut it in half, but you could easily use a 3/4" coupler.

I sumped my stock tank with a competition engineering sump (summit) and just recently put in a Moser 9" rear, and low and behold the sump and 9" don't play well together.

i don't see how welding in a sump in the back would ever interfere with a 9" rear end. I have a 9 bolt on my camaro and the back of the rear end is nowhere near the sump, the front of the gas tank is much much closer to the rear end. All things being equal the back of a 9" should be at most 2 inches further back than a 10/9 bolt rear end and would still have plenty of clearance. What do you need -12 AN lines for exactly?

look sump it once, sump it right, sure -8an line will be plenty most likely, but what happens in the future i don't know. Except that if i need more than -8an that ill need to re sump it. If i go bigger to start off with theres no problem with me getting smaller fittings

Here are some pics of the 9" and the clearance issue's I'm having. It's not really the sump per-say just the the whole rearend to body clearance, and the gas tank itself.
There are two pics of the gas tank to 9" clearance, and two pics of torque arm mount to body clearance issues, and one pic that show how much clearance I have on the rear snubber from the car being on jackstands.

As far as the rear disk is concerend it's the Baer Serious Street setup. 12" rear rotor. I'm not sure if a 15" will fit. I'm Running 18's.

As for the baer 12", i doubt they do, i have LT1 brakes on the rear and i had to grind the calipers a good lil amount to get the 15" draglites to clear so im almost possitive those wont too bad, they look very nice.

1 DwnCam...From your picture it looks like you are running a Jegster torque arm. From my experience, that is probably the best piece out there for drag racing, but you are not going to get away from interference issues even when the car sits at factory ride height.

Actually it's a Spohn Adjuustable Torque arm, but I have come to the realization that there are going to be clearance issues with beefier suspension pieces and a lowered vehicle.

just to chime in there are three baer claw setups, the first comes with an 11.23 (about) inch rotor that fits 15" wheels and larger;
then there is the 12" rotor which fits 16" and larger
and finally the 13" rotor that fits 17" and larger.
straight from baer.

no problem,
and bt283 and anyone else that just welded bungs onto your gas tank, you don't have a problem with corners and running pumps dry on half tanks of gas and less?
i know sumps keep a reserve by the lines in the case of fuel slosh.

check this thread below for pics of mine.... its a modified comp engineering sump, to fit the stock tank, and its slightly offset to the pass. side for clearance with the panhard brace.
I have dual exhaust, and the mufflers arent in the stock location so nothing is really even near it, it worked out beautifully.

thanks man......I made a stainless steel cover for that hole when i first made it way back........I had to dimple it to make clearance for the -10 fitting and hose, as it sticks up quite a bit, but yes it is sealed.

383backinblack- our cars are very similar in regards to motor, drivetrain, fuel system. I'm thinkin that because of going to the 9" route and having it lowered that has caused me great greif. By the way your car is pretty Badass!

ya my car has drag launch springs and koni adjustable shocks and struts.....people bitch at me to lower it all the time, but it has little enough grond clearance as it is, and it suspension works the way its supposed to, so its not gonna happen lol.
which blower are you using? and what do you have for heads etc? I really can't wait to get this thing on the dyno, yours made 780hp at 13psi? is that at the wheels? im at 22psi now, and im not even leaning on the blower yet it will make 30 with a bigger crank cog

Sorry to hear that.
The cam is a Solid Roller Lunati.
250/250 dur 631/639 lift W/114 center.
I still have a million and one things to do before I can fire her up again. Looking forward to that day.

that's fine if you want, I spent $110 for my sump to be welded on. $60 for labor and $50 for the sump, on an almost empty fuel tank I don't have issues going around turns like this setup might cause due to a lack of a "sump" to hold some fuel while turning, in the setup on that picture it could all roll to one side and cause starvation issues.

I had my suspension set up while I had my cage installed. My tank and 9" play well now. While I was having problems with my tank I was and still am concidering Nasty Nates Custom aluminum sumped tank. If you look in the picture the tank is notched in the front for the 9" housing. I spoke with nate and he says it's a direct bolt in with no problems.

is that nasty fuel systems i.e http://www.nastyperformance.com/FuelSystem.html I just picked one of these up, looks nice but it`s pretty heavy compared to stock, it is 24#`s, I know the stock sheetmetal can`t be that heavy
