Fuel Surge Issues?

[No Crust Racing]

Cheers, seems like I'll need some larger diameter fuel hose there then it can step down to 5/16th on the outlet end as per the standard fuel system.

Just thinking any reason I can't fit the pump to the tank directly with suitable connectors and have no hose in between? Mounting heights permitting so it's all level/no load on the fittings.

Question regarding the feed from the surge to the pump.

Given the feed out of the pump and into the fuel system will be 5/16 EFI fuel hose like what's already there, can the feed into the pump be the same or must it be bigger?

I ask only because that fitting is 10AN compared to the 6AN used everywhere else.

My plane was simply to buy AN to 5/16th barb fittings like these. Though I'm having trouble finding a 10AN to 5/16 barb to so I might have to go 10AN to 8AN then to 5/16.

And then just use something like this hose for everything and these clamps.

Im using 8an fitting from surge to my 044 then the an8 5/16 barb fitting from pump to engine. Dont know about other pumps but I know 044 no issues with AN8 feed.

Appreciate the input

Can someone help me find the bloody part numbers.

Rather than use standard barbs and clamps I thought pushlock fittings would be better, but trying to find 6an to 5/16 pushlock is proving difficult, I'm waiting to hear back from Speedflow but if anyone knows let me know.

Also any idea if I can just use standard EFI fuel hose with pushlock or if it must be the specific aeroflow/speed flow pushlock hose?

What do you mean 6an to 5/16? As in you want a 5/16 push lock end instead of barb? the pushlock ends are made specifically for those hoses as they are there own diameters made specifically for those fittings so you wont find a push lock fitting made for convential hose sizes, I wouldnt be using normal hoses on push locks. What is your reason of wanting the push locks over the normal barbs?

[No Crust Racing]

I simply assumed it would be a better/tighter fit than hose clamps (which I'm not super keen on - though they are used in the standard fuel system).

If there's no gain from them I'll just use standard hose and 5/16th barbs.

There is absolutely nothing wrong with the normal barbs and clamps like I said mine have been on for years and I actually could not remove the barb from the hose i had to cut the hose its that tight, imo even when I use pushons I always still put a clamp on as I still dont like to rely on a push fitting.

Potentially you could use a push on -6 fitting on 3/8 size hose as they are pretty the same dia but yeah I wouldnt recomend it.

heres a pic of my setup anyway super simple and reliable.

Fair enough, I'll stick with standard barbs then, cheap enough and I'll add decent hose clamps for safety.

[boostn0199]

Yeah just get actual fuel efi pressure hose clamps and not the 50cent coolant ones and wont have any problems.

[No Crust Racing]

Looking at these.

Had good success with Tridon ones before.

Yeah theyll work. I use the ones in the link.

They look nicer again and a 10 pack on eBay is only a few bucks more. Might get those,

I can see they come in various sizes. Any idea what the OD is of 5/16 hose? I'm assuming the 13-15mm clamps are the go?

Outer diameter is 14.7mm so prob go with 14-16 or 15-17 i cant remember which ones I got. The norma sell really good quality clamps if you want good intercooler clamps you can also have a look at these I use them aswell and have never had one pop off.

Try bumping the boost a bit, the fuel will leak past that Norma clamp eventually given enough pressure. I would be running some new 400 series push on hose at a minimum. I guess I worry about ethanol compatibility and leaks/smells inside the car more than most...

[No Crust Racing]

You don't like these Scott? http://www.norma.net.au/products/hose-clamps/norma/aba-small-bore-hose-clips

Given I was just going to use the Tridon ones and that's all that's on the standard fuel system (using barbs) I'm not too worried about it not sealing.

[No Crust Racing]

It's going to have to use a standard barb fitting at 2 points anyway, as that's what comes out /goes into of the fuel tank.

Plus where I join the surge to standard fuel lines into/out of engine, that's just standard efi fuel hose also.

[scotty nm35]

Yes, but that is in the engine bay, not inside the car. Still, under the heat of the track and hot fuel, the efi hose will soften and the clamp isn't spring loaded to take up the slack. I guess you don't worry about things like that until it happens to you.

[No Crust Racing]

Im not sure about your car, but mine get's pretty hot in the engine bay, yet to see a clamp come loose, not bad for original clamps on a 25yr old car

I understand what you're saying, I just don't feel that it's as much of a factor for me on a car that only does a few thousand k's a year at most and gets very regular eyes on it.

Just getting final pricing for various bits.

Take a chance on this with 2yr warranty? http://www.ebay.com....984.m1423.l2649

Or spend the extra for this? http://www.ebay.com....cc0eef00&_uhb=1

Good luck getting warranty to cover your f**ked motor

I doubt either of those are actually genuine.
