The V8 Owners Forum -

By jove I think he's got it (Apologies to my Fair Lady) :lol: Worth checking the inlet and outlet on the Holley pump if you are gong that route and just need to do the connections once. (I seem to remember the holly having BIG connectors) I think I would still go return to swirl but it's your choice...

How about just coating a set of existing rocker covers in the stuff to make them look like carbon fiber? Ok no weight saving but the bling is there! Ian Or have a look at http://www.gt40s.com/forum/tech-exterior-interior-trim-finishing/14849-mkii-rear-brake-scoops-my-summer-project.html?highlight=su...

I've asked the same question elsewhere Someone said hot fue; vapourises better - see carb engines where the hot water sysem was used t heat the carbs. Is this correct or was that just to stop the carbs icing up? Also fuel injector design is such that the spray and atomisation is designed for better ...

Racer That is good to know but I am sitting between 2 fuel tank in the 40 and would rather the fuel was not heating thus causing mor vapourisation and potential for a fire. On another forum someone suggested moving the fuel regulator close to the HP pump and blocking off the end of the fuel rail. Th...

The swirl pot would not be at a pressure (very small perhaps) as it would be a loop from the tank through Facit to Swirl and back to tank. Only rise in pressure would be if the return line was smaller than the feed line. Where did they put the spare wheel in the MGB? Could the swirl be located there...

What flow rate are your 2 pumps Facit is 45gal per hour If he high pressure pump flows more than that the Facit is not beefy enough and the swirl pot will empty. Hence the need to return to swirl pot A tall swil pot is better - a bit more head of pressure feeding into the High Pressure pump but what...

Been there and got the confused T shirt! Probably best to say there never seems to be a direct answer. I ended up using 8mm inside diameter fuel hose (high pressure) all around and all connectoins are with jubilee clips. I was told this should be good for up to 300 hp and my engine is less than that...

Following on from another thread discussing swirl pots and fuel systems it is apparant that fuel tends to heat up in an EFi fuel rail and this in turn can heat up the fuel in the swirl pot or even the main thank. How much heat is transferred? What is the difference in inlet vs outlet fuel temp? Last...

Chodjinn Sorry no the comment was not pointed at you but to some others who thought it better to run the fuel rail return to the tank. This would mean buying a swirl pot then having it modified to block a pipe off. Or commission a build to your specifications both cost more than standard units! Swir...

Yes that is correct The calculation is what the HP pump will pump i.e draw from the swirl pot. If the feed to the swirl pot is not working (pumping air by the low pressure pump) this is how much running time you have. After that the HP pump will pump air the engine die and if the HP pump left to run...

Have a look at http://www.nfauto.co.uk/ http://www.rallydesign.co.uk/catalog/default.php http://www.demon-tweeks.co.uk/ Plus I am sure many others and then search for swirl pot. all are tanks with 4 outlets Top is return to tank Next is return from fuel rail Next is feed from tank Bottom is feed to ...

Stevie I agree re the pipes but I have seen some people try to yse the original 1/4 inch feed for the return and run into problems. (Converting a small engine car similar to MGB to V8) Try to get 45 gal per hour from a red top through a 1/4 inch pipe! I would consider it foolish not to return the fu...

Another thing to remember is that the return to swirl and also return to tank has to be a pipe of big enough bore to allow for maximum flow rate of the pump or your system will end up working at a higher pressure. Imagine yur car is at idle and the fuel pump going flat out regulator is allowing it t...

Schematic is OK but feed back to tank has to be the highest outlet so any air pumped by the low pressure / facit pump will be sent back to the tank. If not you will end up with a swirlpot that is not as full as possible and if the fuel surges away from the tank pickup you do not have the max possibl...

I beg to differ

this would work as a filter and swirl pot all in one
Put the Facit near the main tank and push fuel to here

Feed from this to the EFI pump

First and last time I saw this setup!
