Fuel swirl pots: opinions on safety!?

[rx7boy]

i still havent managed to get these fitted yet, have been thinking how im going to mount them but until i get all the fuel out and have a look in the tank i wont know.

Old thread revival, but just want to make sure im doing this right and if you have any better suggestions

Pic bellow is how I plan on setting up

This is a really interesting thread never seen it before just had a good read

Mazdarotary parts sells all the bits needed for that setup. You need no return valves too.

Have spoken to clive, he sells the anti surge filters but not any other fittings,

Ah, sorry. Looks distinctly like that is what you want. If your after fittings and pipe try http://www.thinkauto.com/acatalog/intro.html

thats how i was going to do it but not use the metal pipe to keep them away as im sure the hose will do that job once its got fuel in. plus they will move around a bit as the fuel sloshes about so should be all good.

i didnt actually fit mine, still have them if anyone is interested.

Hi,

Was amazed when I read this, then on giving it further thought I just can\'t work out how this is physically possible.. :confused:

Previously I ran a swirl pot (buried in the rear wheel well, and yes lines came through the car but they were metal braided). It was 1l, and given the setup it\'s just not physically possible to drain it if correctly installed?

The return line from the carb/injector rail will go back to the swirl pot not the tank (or it should do) and the take off is at the bottom. It is filled from the top by a lift pump from the main tank capable of outdragging the engine requirements (red top or something), plus an overflow from the very top that vents back to the main tank. So the draw is only the fuel that\'s actually used.

So for you to drain a 1.5l swirl pot you need to have ingested, and not had returned, 1.5l in the time it takes to execute the /corner/ and enable the pump to refill the pot.

So either the lift pump isn\'t filling the swirl pot quickly enough (needs upgrading) or the return line has been fed back to the main tank instead of the pot.  So I\'m lost as to why your swirl pot needs to be 3l.

With this set up correctly installed I could run the race car dry of fuel, and this worked with other race cars too, both injection and carb on road tyres, race tyres and full slicks. All of them had the lift pump and pot hiding in the plated off wheel well.

Nowadays I have an ATL fuel cell, with an in-tank high pressure pump direct to the main fuel line. It sits inside a baffled collector pot and is pretty good, but frankly less efficient when you are scraping the bottom of the tank than the swirl pot twin pump system. It will surge when we get down to vapours. It was installed for extra capacity only.

I\'m presumably missing something so wait to be educated!

Cheers

Correct, we have never had problems with swirl pots, even with 8 injectors on the drag car, just has to be the right size and also you have to bear in  mind the contant return from the fuel rails.
