Ok guys, I have an ek hatch and I'm sumping the tank for a dual Bosch 044 setup... Basically im trying to figure out the best way to vent the tank... I'm pulling the cover off where the factory feed and return are and making a plate to cover that up... I'm going to have a fitting welded into that for the return... Is there something I can put in that plate to act as a vent? The car is mainly track car but will be driven on the streets... I just wanna make sure I do this right so I don't have an issue of fuel sloshing out or an extreme fuel fume smell or anything like that... Any photos of how you have your setup done would be much appreciated

 

i run the fcs tank and i just leave the gas cap crack for the vent.

 

What's wrong with using the factory vent?

 

What's wrong with using the factory vent?

its what i did

 

factory tank, with a sump, sux.

 

why is that matt i keep hearing people say this, and have no clue why necause i have never had an issue with mine at all

so fill us in on what the issues are

 

lol i just always hated after braking the big end that i had to wait for the fuel to fall back in and let the pump stop cavitation... or when you get low on fuel by accident it pretty much won't go anywhere lol

 

lol ahhhh i was expecting some big explenation lol

 

plus the rust aka e2O3.nH2O

 

agree with rusting

 

That's why I went with the fuel cell lol

 

fcs fuel tank is a top 10 item on my car.

 

Look into a surge tank

 

I am curious how most people are sumping their stock tanks, are you cutting out a chunk of the stock tank and then welding in the sump on? Or are some of you guys drilling a couple holes where the sump is gunna go then welding the sump on?

 

Yeah that's helpful for Randy's thread.

Randy, I used the factory one homie.

 

I used -6AN sized one way check valves for vents back in the day before the NRG and FCS cells came about

 

I'm running a stock tank sumped w/no rust or probs (besides like stated earlier if u slam on the brakes hard) but it hasnt been a big prob for me. I stripped my tank and drilled 5-6 holes and then welded a sump we bent up to it. Re-undercoated the tank and it's been good to go every since, AND the stock fuel gauge still works great..lol. I used the stock return off the cap and ran rubber hose to behind the bumper hope that helps man

 

Randy, I am doing the exact setup you just named (Factory tank sumped with two -8's for the 044's, and -8 return welded to a cap in stock location) and I am going to use the factory vent. No point in overcomplicating things...

 

Roughly how much gas do you have to keep in the tank to avoid issues?

I noticed in a vid lately someone would shut their car off right after passing the 1/4 mile mark. Could tat have anything to do with having a dumped tank and trying to avoid issues during breaking?

 

Mine doesn't do it when it's a 1/2 tank or fuller, ....u could always build a surge tank sobit has a gal or so on tap at all times

 

yeah i always shut off right after the qtr no matter how much fuel is in the tank.

 

Seems like a lot of hassle.running a oem tank.having to fill it up so the.pumps don't starve or to buy a surge setup which in turn will prolly cost more then replacing it with a FCS.one and solving all those issues while saving a ton of weight .

 

Well if something was offered that held more than 5 gallons, then I'd be interested.... I have no intentions on driving my car around with a gas can full of e85 hanging out in the back....

Thanks for all the replies everyone

 

FCS offers a 9 gallon and a 15 gallon. Oem location

 

Interesting, I'll have to check them out
