fuel pump help
davidinhull - 30/6/10 at 06:33 PM

Hi
The previous owner of my car installed an electric in line fuel pump in the engine bay, despite the clear instructions not to do this. The pump has now died (overheating I think)
I obviously need to replace it. For my limited skills, replacing it in the same position would be easiest. Does anyone know of an in line 12v electric fuel pump that would be suitable to locate in the engine bay ( bolted to the bulkhead)

Thanks

David

High or low presure ?

If low presure the webcon Huco pump is designed to suck from the engine bay. I have one in mine feeding the swirl pot.

1.6 litre fiat twin cam, twin webbers
unfortunatly I have no real idea of pressure, but it'll be sucking from the engine bay as far as I can tell it's the only fuel pump on the car
(you'll have to excuse my obvious lack of knowledge!)

The one in my link is ideal for webers and is sold as such by webcon. I used it to fuel a set of 45's

that looks a good pump, it says delivers at 1.4psi in that case do you not need a separate regulator?, seems suitable for most carbs including motorbike ones then

If you join Guy Croft's forum and ask the question one of the forum members or Guy himself will no doubt be able to quote you chapter and verse.
Webers are designed to run at 2.5 - 5 psi. running pressure (optimum is 3psi). The easiest way of finding out is to fit a Malpassi/Filter King regulator/filter in the engine bay area. Make sure it's the version to which you can attach a pressure guage to check fuel pressure. They are not partic. cheap but improved my T/C no end - you can also swop it from car to car when you change them. I bought a metal filter bowl version as glass ones are strictly road use i.e. glass bowls can break in an accident so are not allowed for competition.
The recommendation is to fit the fuel pump under the bonnet or ideally if overheating did cook the last one near the tank with a non-return valve up-stream and close to the pump so fuel doesn't drain back.
Facet do a Silver Top Interrupter pump which should be OK or there's a cheaper version sold by Rally Design under the RMD brand or look at Fuel Systems.

HTH.
