Fuel System Revamp

[Barry.Cook]

Last year I finished up taking my Fulvia HF off the road early as I found the fuel pipes at the rear of the car had been turned to a black mush by the ethanol in the E5 fuel. It felt like a close escape as the previous owner had fitted a Facet electric pump above the heat shield above the rear silencer. As the weather is now finally drying out a bit I'm keen to get it back on the road. This is what I plan to do:

1. Re-site the electric fuel pump in the boot.
2. Replace the cheap chinese fuel pressure regulator with a Filter King fitted to the left hand side of the engine bay.
3. Replace all the fuel hoses with ethanol resistant pipe from a trusted source.

Couple of questions before I do that.
1. From previous posts I know some of you have fitted electric pumps in the boot. Did you bolt them directly to the boot floor or did you mount them on rubber mounts and have you boxed them off to protect them from other stuff in the boot?  As ever if you have photos that would be great.
2. The Filter King is available with a 67mm or an 85mm filter bowl. I suspect the 67mm is adequate but what have you guys used?
3. Did you opt for the option with the pressure guage for initial setting up? With the delivery pressure range it looks to me although it needs to be set near the bottom end of the pressure range anyway.

Thanks in advance for any help.

I can say Facet work well in engine compartment and will make the integral filter more accessible. If possible use Cavis Benz green "plastic" 7mm pipe for all plumbing (return use 4mm). Use a disposible inline filter from tank feed to facet (hence another reason for front mounting). Use the larger filter king and make sure it is glass not plastic bowl. I use a temporary inling 0-10 psir gauge between the filter king and carbs set to 3 psi and then remove. Various sources for cavis benz (omicron , ricambio).

Thank you Tim. That's very useful advice.

Mines a series 1 so may not be relevant and you have probably made decision anyway but for what its worth fitted Facet Red Top with correct low pressure spring from Omicron  in boot bolted to wheel arch with rubber mounts.  Very little noise in cabin or boot - but had cube type facet before which was awfully noisy.  No regulator - maybe another thing I need.   Oh Dear

On my series 1 2c with no fuel return line.
I have a priming pump fitted next to the tank. A switch with a warning light, once the light stops flickering the carbs are primed.
 Last year, I fitted a new mechanical fuel pump from Omicron and  new cavis benz green fuel pipe, supplied by Ricambio .
I've had the 67mm glass bowl filter king fitted for about 20 years and has always run with the pressure it was set at when supplied, including climbing over the alps a number of times.
All feeding my twin 32Dhlb Dellortos.
The only problem I've ever had was last year, when the fuel pipe stubs in the old fuel pump² pulled out, thanks to the ravages of ethanol fuel.

Thank you to everyone who posted comments. It's all back together now. New piping throughout and the Filter King all fitted. Omicron very kindly set the Filter King to 3 psi. Fired her up this morning and she immediately fired into life. She's never done that before and she sounded very sweet. Will get her out for a longer run this week subject to getting some decent weather.

By way of bringing the thread to a conclusion below is a photo of one of the fuel lines that I removed. I would encourage anyone who is not sure of the condition of their fuel hoses to check them before venturing out this spring.
