I'll have to see if I have any picks otherwise ill take some this weekend. I use my standard lift pump before and 2 Bosch 944 pumps after.

MY wagons surge tank done by MR enforcer , a while ago still not on the road not the best pic but can see it . Some original photos have not been recovered yet.

Here is a photo of where my surge tank sits and some of the welds ImageUploadedByTapatalk1352576675.301866.jpg (http://www.calaisturbo.com.au/attachment.php?attachmentid=57225&d=1352576678) ImageUploadedByTapatalk1352576460.846144.jpg (http://www.calaisturbo.com.au/attachment.php?attachmentid=57223&d=1352576464) ImageUploadedByTapatalk1352576472.556671.jpg (http://www.calaisturbo.com.au/attachment.php?attachmentid=57224&d=1352576476) www.facebook.com/redstarfabrications (http://www.facebook.com/redstarfabrications)

In my experience round made surge tanks are your best option reason being when there made square or rectangular it will build side wall pressures and will have a better chance of leakage at the welds. I'm also going to try Out the new sonic intank pumps a friend recommended to me shortly,they flow Heaps more and a suitable for ethanol based fuels in particular.

All comes down to the fabricator and welder. I just finished doing some xr6 surge tanks and pressure tested to 80psi with no problems at all and the were made from sheet aluminium. Something else I have also started doing, since getting my own sheet metal folder, is to have less weld and more folds, adding to the overall strength. www.facebook.com/redstarfabrications (http://www.facebook.com/redstarfabrications)

A properly plumbed fuel system shouldn't allow the surge tank to build up much pressure even with a high flow pump

There should be a return line from the top of the surge tank back to the main tank. So any excess fuel goes straight back to the main tank and therefore the surge tank should always be at the same pressure as the main tank. The main tank itself should be vented to the outside to allow for temperature changes and the fact fuel is being sucked out of the tank. I am not sure how VL fuel tanks are vented though. Is it in the fuel cap?

Its in the fuel filler tube also one of the vents runs to the carbon canistor if fitted

Cool, thanks mate.

these look the part !! .. how much was that setup if you dont mind me asking, and who did the work ??
