Fuel pump in Vixen

[Stevo302]

Hi guys, I have a solid state (Facet?) fuel pump to fit to my 2500. Wondering the pros and cons, where to install and a little help for the wireing. I dont use the car all the time and sometimes wile standing the fuel goes back past the engine mech. pump towards the tank and takes ages for the fuel to get to the carbs. Thats my main reason for a new and better way for fuel to get to the carbs.

Cheers.

I thought the type of pump determined if it was fitted near the tank or near the carb. but I may be wrong.

I've never fitted an electric fuel pump so this may be incorrect but I would also fit an inertia fuel cut-off switch incase you have an accident. You may also need a regulator after the pump as the pressure may be too high for the carb. Finally if it was me I would also leave the mechanical pump fitted so you can still use that if the electric one packs up.

I'm sure someone else will be along soon and correct what I have said.

Hi,

I have one fitted for similar reasons. Fitted it in the tank bay attached to the rear pax side wheel arch. Fitting both a regulator and inertia cut-off are good ideas. I don't run a regulator (Essex V6, 40 DFAV) but I did check what pressure the pump would deliver and what the carb would accept, luckily they were close enough!

I also have a key operated cut-off switch as an anti-theft device.

Thanks for the replys.

Yes well worth having it fitted with a safety device in case of an accident also wire it so it does not start until the alternator sends a current mine was wired direct to the ignition so when you turned the key to power without starting the pump came on not a good idea will be changing.
Fine if the carb float works ok but should it occasionally stick open and you leave the ignition on with the engine off then you can have a very flooded engine also should in the case of an accident and there is a pipe damaged and the fuel pump is near the tank then well you can imagine the result not a nice result hot engine and sparks.

I think that's exactly what this application DOES require. As I understand it the problem is that the mechanical pump is drying out so isn't pumping fuel so the car won't start. If the elec pump only comes on with the alternator giving power it wouldn't solve the problem.

I see your point as it is when the key is turned half way you hear the pump come on then when I hear the fuel hit the carb I turn the key and starts first turn.
My big worry is the safety of this in an accident??.

In an accident you need an Inertia switch. Maybe you should try LISTENING instead of TALKING when someone gives you advice.

My Taimar came converted to electric fuel pump when I bought it but I have added an inertia switch very similar to this except it was listed as from a Sierra and cost a tenth of that!

Know idea on the Vixen but on mine there is a return pipe to the tank so when float shuts off the pump isn't "dead headed" fuel has somewhere to go.

[pridaux]

Yes steve your correct and Adrian kindly sent the instructions to me weeks ago as to the fitting instructions just have to get round to fitting yes there is a return pipe as well however its just important that others realise the danger of a fuel pump that continues running after an accident.

Don't think Vixens have a return pipe as standard. But I guess it'll depend on the carbs. If it's a 2500 I assume it's running SU's? Some of those have an overflow / return vent and some don't.

Don't think I will bother now unless I can take it somewhere to get it done correctly. What about those in line fuel hand pump things? Could put one of them in?
Thanks for all the comments.
