How would one feel about having an accusump in the passanger compartment? 3 qrt unit. Oil is a fuel of some surt atleast is flamable.

If you do put it in the passenger cabin, I'd recommend using flex line from a bulkhead fitting.

In my road race car I mounted it (like most do) in the passenger cabin, near the exhaust tunnel. I figure this is about the safest place for it to be. Also because there is just the single seat there is lots of room for the 3 quart unit.
I also figure on road racing it is unlikely to get in a really, really big wreck that will rip the line.

On rallying though, its a bit more likely to happen, so I'm trying to mount them up in the engine compartment. We went with a 1 quart unit for two reasons: because the lower g-forces that are less likely to uncover the oil pickup, and will be easier to fit in the engine compartment.

I guess I'd try to keep it outside the passenger compartment if you can, but if you have no choice, use stainless flex lines.

I have a used Accusump that came with my car, that I'm not using.

Not sure if you're interested in buying used.

Thanks for the offer, we have one but are jus trying to find the best location, it happens to be the 3qrt High pressure unit, so it big once you all all the fittings on it.

Ive heard of windshield washer resorvoir in the cabin not passing tech/having difficulty so i bet they will have a major issue with it if you plan on rallying

um...i think there is a rule book somewhere...you could try reading that....

Um yeah not a rally car so your rules don’t apply. Just looking for a general consensus on it.

My Colt has an accusump in the cabin when I bought it, and it had done stage rallies with it installed.

You could use braided lines to help the line issue, but you have to do something with any unit that has a gauge on it. That will be the problem to be smashed and spray hot flammable liquid all over. I would try to avoid it in the passenger compartment, unless you put a well sealed shield over it and had a drain hole under it.

Good point Mark!

I'm not sure if the oil in the accusump would actually get hot or not--seems like the oil in the lines that is going back and forth, getting cycled through the oil passages would. But the bulk of the oil will never leave the cylinder (I think).

I will say that the amount of carnage one of these things COULD unlease is pretty amazing. I was working on on unit that was leaking a bit--fitting was not tight. The pressure gauge I think said zero, or very close to it, because I thought it was not under pressure. Then and I accidentally bumped the valve.

Big mistake. Even at less than 5psi, oil went freaking EVERYWHERE. Was a huge mess, I was covered head to toe, had to go and take a shower immediately after it happened. Took me an hour or two to get it cleaned up.

I can't imagine what 50psi would have been like. Probably would have taken my head off. I really can't imagine what it'd have been like it it was scalding hot and near a flame.

The danger potential is there for sure.

I'm actually kinda surprised Accusump doesn't make a recommendation one way or the other. Most units that I've seen are mounted in the cabin. In the trunk would be ideal!

I never really had thought of them being dangerous as they are routinely seen inside the cabin of road race cars, probably ok there. But road race guys just can't crash like we do.
I think now in a rally car (if for some reason a gravel rally car needed a dry sump) I'd mount it in the trunk.

Gone fishing

As far as the oil being hot, yes, if you stall with a hot eninge, and have a prolonged re-start, the accusmup will refill with maximally hot oil.

I expect that the main reason to mount them in the passenger side seating area is to allow the lever to be reached by the driver to start oil flow at start-up, and close the valve at engine shutoff. I doubt it has anything to do with safer road racing, just my IMO.

If you want to have the non-dry start-up feature of the accusump, then you either have to somehow arrange the lever to be within driver's reach, add a linkage system or cable system to get it out of the passenger area but controlled by the driver, or use the electric control valve option.

If you only want the advanatage of an accusump to avoid temporary low oil pressure, then you don't need the valve and it can go anywhere.

With relatively low g forces of rally cars vs some road race cars, are these of much use to rally cars? Weightlessness in yumps does not last very long either.

We decided that an in the trunk mounting location would be more ideal, the thought of the hot oil in the cabin like that really scares me.

How big is this thing? Could you put it in the engine bay? In front or behind one of the strut towers, over the inner fender?
