Part No. FHO15
Car Universal
Description Black cotton overbraid
Int. dia. 12mm
Price (per metre) £3.60

Looks like the stuff....

No way would i run that , but hey its your car. If your on a tight budget run a length of s/steel tube or aluminium tube its about the same price as that stuff but a lot better

Am pretty sure this can be dual fueled with the addition of a second fuel nipple on the second otherside of the carb

Not sure on that, not seen anything about it on the sites I have been visiting.

Would be intrested to know if it can be done though.

Most people would run either a braided/high performance line or a steel/s/steel/aluminium line under the car then either a rubber hose or braided/hi-perf to the carb

Ok next question, If i fit this 1/2" stuff to my current engine/fuel setup will it have adverse effects?

Should I just replace the crumbleing rubber I have, with cheap equivalent rubber, till the new stuff gets fitted.

A quick search on jegs shows that you can dual fuel your carb mate

Jamieg285 · « **Reply #31 on:** April 20, 2006, 02:39:29 pm »

I saw that, but assumed it was for dual inlet ones only. I still haven't seen info on how to do it.

There's nothing mentioning it in the Carb manual.

Jamieg285 · « **Reply #32 on:** April 20, 2006, 02:39:56 pm »

Maybe an email to Edelbrock tech support is in order.

55starchief · « **Reply #33 on:** April 20, 2006, 02:40:57 pm »

Pretty sure you will find a blanking cap on one side of the carb and an inlet on the other

Anything that I've missed?

Looks good mate, I would ask andy for a price on the fuel pump and filter, he might also be able to get the other stuff seeing as he is a racer your choice.

Jamieg285 · « **Reply #36 on:** April 21, 2006, 09:38:41 am »

Also a couple more questions...

Anyone know how the pipe attach at the fuel tank. I assume that there is a fixed hard line coming out of it, which you clamp a rubber hose to.

Also, is it OK to have the fuel pump attached directly to the hard line, or should it have a rubber hose both sides, before joining the hard line?

That is the plan at the moment. First I want to make sure I have the full list of requirements.

I wouldnt bother with a Red pump mate the flow rate is to low for your motor especialy if you plan on doing any updates soon. I would look at a Blue minimum but a black if the budget is there. I have an aeromotive fuel pump and regulator that flows 150 gph+

Banjo Fitting to Carb

Can you not get away with a straight conector to the carb mate? seems a shame to restrict the flow as it enters the carb

According to the Holley page that Chris posted :-

500bhp(more than I will ever be going) = 250 lbs/hour
250/6 = 41 gallons/hour.

Red more than covers that, so why would I need to go higher? At this stage the carb needs to be limited to 5.5 psi, and when I go EFI I will need a different pump anyway. Am I missing something?

While on the subject of fuel fittings . . .

Can someone recommend a Swirl-pot for the Camaro ?

Cutting out when braking into corners is getting irritating.

That comes with the carb, however the instructions (and past experience) show that there might be clearance problems with the air cleaner.

It's not definitely going to be used, but ready to hand 'just in case'.

Jamieg285 · « **Reply #44 on:** April 21, 2006, 09:58:18 am »

Oh, also forgot

- -6AN braided hose for between regulator and carb - not been able to find a -8 AN fitting that will fit carb.

Im a belt and braces man mate, I would rather have a bigger pump and it work at half its capacity than a smaller pump working almost to its max

Can a fuel system that is too large hurt performance? No, it assures your combination will reach its full potential: the needles and seats will shut when the float bowls are full. Conversely, if your fuel system is marginal, fluctuations in battery voltage will cause fuel flow changes from run-to-run which affects the float levels in the carburetors and out-the-window goes your consistency! So how do you know if your volume is adequate?
