Hmmmmmmmmmmmmm I'm not following what you mean by fitting the pump in the centre section so as to double the surge tank size Buddy

OK, that makes some sense now Peter, although it would delete the need for a return line, I find it hard to consider as the regulator would need to be turned down so far to negate some of the pressure for regulating the pressure and flow that it may limit regulating ability, Im probably wrong but would like to hear if my synopsis is incorrect. That would be mounted just below the pan on the underside with minimal fuel line feed.

Peter, Im aware of what you discussed regarding the anti return valves, but the "T" piece after the filter with the single supply line to the fuel rail and the bypass back to the tank has stumped me somewhat if im reading this correctly. Fuel flow past the pump will take the path of least resistance, therefore the pressure requirements of the rail will not be met by a bypass at the "T" junction. Am I reading this all wrong?

Gareth Think you have a valid point, so revised the return which in actual fact doesn't even need to be a pipe as shown but just a void the size of a $0.50 piece. Cheers John

Understand Peter Sinse this was never destined to be a track car, the reality of dramatic weight shift isnt a concern, however, and I say this with all respect, as the centre of the donut tank will need to be disected so as to accomodate a uniform surge tank, I could insert and weld in 2 baffle plates.

Hi Pete The surge tank has a single return point to the tank, I'd approximate this to be at the 2 odd litre level, therefore the surge acts as a deterrent to eratic fluid movement in the tank itself, or, as a baffle of sorts. With the low pressure pump feeding this reservoir, I doubt that the surge reservoir would deplete to the point of starvation. Peter, I'm not arguing against what you are saying, more so discussing the pro's and con's and if I'm wrong or youre right then at least we come to some decisive conclusions as to its functionality or improvement

Peter, Your words are always welcome, and is the play on them LOL The capacity of this surge design is 2.44 litres, negates any requirement to build baffles in the existing tank, increases over all capacity to close to 65 litres, appreciate it looks complex but in actual fact is pretty simple, as far as simplification the inductive fuel level sensor is a major KISS item, and the fact that both pumps are outside the tank probably make for a no maintenance solution of the tank long term. Cheers John AR ??????? Bruce cut back on the tomato leafs

I honestly have to stop smoking those tomato plant leaves Bruce Leno in Taralgon keeps sending me, and you lot need to tell me when I'm totally off track with some of the SH*T I come up with. I tossed and turned all last night thinking about a surge tank solution, then an epiphany around 1:00am I have space for a surge tank in the middle of the donut tank for crying out loud ! So I sat down tonight and drew up this quick cut away of the circuit, now if I'm still way off track, for crying out loud someone slap me, otherwise any learnered comments will also be appreciated. Cheers John

Hey professor welcome You do know that we are on an Island, although a charted one, I'm sure that Gilligan, Ginger, Maryanne, The Skipper, and of course the Howles will be happy to help. Just kidding, always good to see a fellow Zedophile from across the pond in our neck of the woods and believe me you will find a hell of a lot of members here with a wealth of knowledge ready to assist. Maybe tell about and show us more of your "Having potential" build and describe some of the issues. Cheers Mongo the Ape Man

been following this silently. So cool, you should just take it to a Nissan Dealer and have them park it on display next to a 370Z Great work

Matt Looking at your pot makes me think that maybe a large air-con reciever dryer would do the trick also, they are rated to some 300 psi so fuel pressure wouldnt be a problem. Im thinking that sinse Im deleting the original fuel tank in favor of the LPG donnut tank sitting in the wheel well that I would have more than enouth options to mount one on the undercarriage in a safe location. Cheers John

Watch those Ph levels and make sure the timers are set correctly LMAO

He forgot to wear his respirator again and obviously was checking the Porsche lamps found a HID ballast controller had failed and spent to long inhaling down in the bunker again

Hey Matt Think we would all appreciate seeing the set up, thanks for the words of wisdom and experience. Someone get Mr Leno a Cuban cigar, no wait, make that a box of Cuban's. Good thinking Juice (Thats like Jay and Bruce joined together) that could work pretty well. Cheers John

Alan, haven't seen you post for a while but you always add valued posts, yep no doubt its in a precarious place, however Id have to say that because its in a high position within the 1/4 and also not encased within a steel structure that it would need to be a hell of a hit to rupture it as the only thing impeding it internally is a plastic trim. That said, I'm not discounting your comment either, its a valid point but I think the chances of it happening would be very low, had it been sitting at floor pan level I would agree with you whole heartedly. Cheers John

You agree then ? LMAO New mod on yours now? Us Bavarian's have to stick together lol Cheers John

I was thinking maybe tuck an air con reciever dryer in the same area and rig it to the tank as a surogate expansion tank? Otherwise, how would they know? The tank as is is hidden behind the trim work and I doubt they would know it even exists.

Ok a new discussion point Crew Was surfing the net as I always do as I had an idea a few days ago about surge tanks and wanted to see if anyone else had considered tried or succeeded in doing so. In the S30's theres an expansion tank sitting tucked inside the RHR 1/4 panel, I found on Hybrid that apparently someones already used this as a surge tank as per the pic attached, but there is little info available as to its success, so question for you all out there, has anyone done it in OZ and to what degree has it been successful? By my calcs, it would be around 2 liters in capacity. Cheers John

Back onto topic LOL

And dont forget, he's not far from Loy Yang A, Loy Yang B and Hazlewood power stations, bet he has a cable jumping power straight from one of them to a bunker under his shop LMAO

Now the truth comes out ! Not only do you look like Jay Leno, but you must have his bucks also and we now know how you make your money !!!!!!!!!!!!!

These are the brackets the head lamps slide and lock into, a very simple arrangement where the rod rotates and locks as the headlamp is pushed in and then seats itself into the guide at the rear of the bracket assy. Apparently a story on the net reporst that you dont want to own a 997 in Amsterdam, apparently pot growers will rip the lights out of parked Porsches as soon as the owner is out of sight as they work extremely well in hydroponic set ups LOL

Yup. If Bruce dosent want it as I offered it to him first, you have dibbs Scott. I removed mine and its in mint condition, my battery's going in the rear of the car. Cheers John

Hey Garreth I will mold the buckets on the new nose to match their positioning, I need to order the 2 mount brackets that they lock into which will be seated on the nose, kind of a plug and play arrangement.

Welcome from across the pond Bud, Peter Mc will be along sooner or later and see this thread, and apart from a number of other guys on this forum he will probably give you the best opinion on what your up to and aspiring to. Cheers John
