Slightly modded 87 vette sending unit...

 

Since I've been asked to post more detail....

It's a Speedway Street Rod poly cell. I got a 87 vette fuel tank sending unit off ebay and put a new pump in just for good measure...

I modded it slightly to accept -6 an fittings for supply and return -6 is plenty for my meager 500HP. Due to the depth of the cell and the anti slosh foam I was not able to get the stock fuel level sender to work so i just put in the after market stick.

the top is a piece of sheet metal with 1/4-20 bolts welded in to make studs to moun the sending unit. The sheet metal is then sealed to the cell with RTV and 1/4" blind closed end pop rivits.

I use a AC Delco G632 stainless fuel filter.

The foam is straight off the Speedway site. I left a 4" square well in the foam where the pickup and pump are. The stock (87) foot screen is positioned via the hose that mounts it to be just touching the bottom of the cell. I used Oetiker stainless ear clamps to secure the hose to the pump outlet and to the supply tube. I used Aeroquip socketless hose and fittings until I can fab up the stainless tube where I want it...

I have a plumbed in an electric fuel pressure sender and it reads 49-51 PSI all the time.

I sweated (it;s just soldered in) out the unleaded baffle in the filler tube and use some silcone hose to connect it to an un-vented billet alloy aircraft filler cap. The stock 87 vent was used with a piece of oem fuel line. BTW the filler cap cost almost as much as the entire rest of the setup.

Note that this setup has only NO more tip over protection than a stock system.

 

How did you mount it to the 'Vette? some details,, even some pics would be appreciated. ty.
also, what do yuo figure the distortion it can take in a crash, w/o tearing open? Did you go with the cell for saftey?

 

Here's a low cost alternative



flip your monitor to read the fueling instructions

what's the weight difference, if any, beetwin a fuel cell and the stock gas tank, with same capacity?

 

I have a bolt on cross member in the holes that the rear sway bar mounts to and it bolts to the rear most crossmember on my '71 frame using the supplied brackets... It was about a 30 minute job.

It's pretty tough... I will use an ATL or Fuel Safe unit when I get closer to completion. Safety... NO Cheap easy and fit my CUSTOM bodywork. I have inside of hatch back and roll cage where you have tank I think.

For safety I have a 5 lb on board halon system with three nozzles... Fuel tank, cockpit, engine compartment I will prolly add another 5lb automatic unit for the cockpit as a separate system.

 

My apologies as this is a little off topic...but where did you get your extinguisher? I want to have 2 rollbar mounted extinguishers as big as I can fit. Halon is the type that won't corrode your engine compartment right?
Also, since your gearing up for competition, are you running a fuel shutoff valve? I have a post running but no responses. Do you know where I can get an -8an one?
Thanks

 

Safecraft via PitstopUSA I think, I just moused around a bit to find the best price...

I'm pretty sure Halon is non corrosive...

No valve yet. I just kill the fuel pump with the master cutoff. Why -8? you looking for BIG Power?

 

Thanks, I'll shop around for the best price also.
I agree, I think I remember reading Halon is the non corrosive chemical.

I found a nice valve from Kinsler, should have it by this weekend.

I ran -8an b/c I wanted to play it safe. Once everyone on here starts running turbo's and SC's I'll want to play too so I figured I might as well plumb the car now for big power in the event I actually go that route in the future. Its a cousin disease of the "while I'm at it" flu. The SS teflon braided lines also make repairs, modification & replacement easy.
