Wild Horses fuel accumulator - leaking

[Stock Farm]

I’m using this accumulator, from Wild Horses and it’s leaking (looks like around the gasket). I’ve removed and installed using a little oil, no oil - nothing’s working....very frustrating.

Anyone have this issue, recommendations?

Thanks

Relighted and check all the fittings, it’s leaking from somewhere
Gasket bad?, thread sealer bad? Is it loose ? Is the hose loose? Etc
Could be dripping down the fuel line from something up stream too, housing cracked etc

Sorry to hear that Stock Farm. I'm not aware of any ongoing, or past issues (of course%)) that might give us a clue as to what's happening in yours unfortunately.
Got pics of the surface of the seal and canister we can see? Wonder if it's possibly due to a machining error having something angled off-kilter or something.

Is it a new install, or have you been running it for awhile and it's just now started to leak?

Either way, give a call in the morning if you have time and let them know. If it's something they know about then they may have a fix. Otherwise they can send a new one if you do not have a fix by then.
Especially if it's a new kit. Even if it's been sitting on your shelf for awhile I don't think it matters because it usually takes a very long time for the large o-rings like that to dry out enough to be troublesome.
But if it's been running awhile, who knows what with today's materials and fuels.

Good luck.

Always the best method sometimes. Give the seller a call. WH always great about providing input back..

Great vendor

Thanks Paul - I do appreciate it and I’ll call you tomorrow.

Spent the day chasing for this down and it’s not the seal, it’s the return line connection.
Looked like the seal as it pooled around the rim...

As you know the base is modified for return line and that’s where it’s leaking.

Any other options out there for accumulators?
This is a new install (put in a Fox Body 5.0).

Thanks

Looks like it's the only fitting not pre-sealed too. Any chance you've already tried some teflon tape or sealing goop to stop the flow?
Does not look cracked thank goodness, so maybe a little thread sealer would be enough.

the company I work for had allot of issues with fuel leaking past threads in fast recovery aircraft pump systems. so much so we resorted to sealing threads with epoxy. it looks like your fuel return line threads were not sealed.

 

[Stock Farm]

The return was sealed, the picture was taken after I removed the teflon tape off.

Rustyturck what epoxy did you use?
The return connector screws into a pretty thin part of the housing (like less that a 1/8”) so may be a good idea to epoxy that one in, the others are fine.

Thanks

Everyone that I know that was running an accumulator, has deleted them. Too many issues with vapor lock, and fuel pump problems. Run a HP pump close to the rear tank, straight to the fuel rail. That’s it. If you’re wanting to keep your aux. tank, most just use it as a transfer tank.

Yea, I’ve read both sides (works well and it doesn’t) - I really want to use both tanks.
Feeding the main with Aux is a good option, but I’d prefer having each tank feed the motor based on which tank is selected.

Many people drive the Bronco (wife, kids, friends...) and don’t want to risk someone overfilling the main by accident.

One more time, JB weld, will seal anything. But make it clean first. That or ARP thread sealer, like white fluffy frosting.

Not everyone Mark.;D I still run the accumulator and have not given it much thought until seeing this thread. I spent a few seconds making a diagram, something like this. I guess this would be an argument for not running the accumulator.

TANK---Low Pressure pump----Accumulator---Filter---Hipressure pump---filter---EFI

VS

Tank w/Hi pressure pump---filter---EFI

My reason for keeping this set up is the same as it was when we first installed it years ago. Keep fuel starvation from happening at low fuel level especially when cornering. If you keep your fuel level up you should never encounter the issue the accumulator was designed to solve.

To the OP if you can't seal it up no problem taking it back or swapping it out for another one. You mentioned the side (aux) tank and putting that in the mix is a whole other discussion we tend to go with the transfer pump idea on that issue.

We blended our own epoxy system base on a base epoxy Novolac resin. for commercial use use JB weld just make sure it is fully cured before exposing to fuel. epoxy's like to cure while hot heat it up to 100F during cure. flush all metal with acetone before applying epoxy.

I think this set up is better.

The 1/8” extension make it easier to screw into the housing and use a hose clamp. The original set up (first picture) the bolt hits the housing so it doesn’t tighten up well (at least that was the case for me).

No leaks, l’m confident it will be good for years to come.
