Fitting an lelctric fuel pump, Dave Lanes Singer

[Dave Lane]

I did away with the mechanical pump decades ago as i had one that pumped a small % of fuel into the sump as well as the carbs - not a great plan .
Anyway theres two real places to fit them , either in the engine bay or up front . theres for and against on both
Engine end pros - easy to fit - easy to connect up with nout to do at all at the tank end
Engine end cons - They can look untidy and if your a purist they are wrong for the car
Tank end pros - hidden out of sight or harms way therefor keeping the engine bay neater .
Tank end cons - very involved to install initially , tank out , rerouting of fuel pipes - another hole in the floor and all in all a pain to do.
Ive done both - one on each car , Singer got a tank end one and the Vusky engine end , mainly as its no show car and therefor what it looked like didnt matter .
Theres various pumps on the market , Facet and SU being two - Facets can be noisy so i went with SU ones but the choice is yours . On the tank end one however the outlet pipe is 8mm and of course the main front to back pipe is 1/4 inch ( 6mm ) so i needed an 8mm to 6mm connector , these are available in straight or 90˚ bends - i fitted the 90˚ one on the Singer . fit a cover over a tank end pump to stop it getting hit with all the spares we tend to carry
Its also a great idea to fit a shut off tap esp. on a tank end fitted pump , you can change the pump without draining the tank and even remove it full of fuel . use a Banjo connector for the tank fitting on front mounted pumps
Some WILL need a pressure regulator as the output is too high , Facet ones will need regulating - the SU ones I used did not .
Safety note
Electric supply must be fused
A manual dash mounted switch is very handy as is an "on " tail tail light .
Fit an inertia cut off switch so in the event of an accident the pump shuts off - you can get the supply from the alternator or use the oil pressure switch as a shut off - no oil pressure no pump although you cant prime the carbs wired like this .
Supply must be taken so the pumps not live with the ignition switch in the aux position .
There are tank and engine end pumps - suck or blow - make sure you get the correct one .
Thats about it really

Pump fitted well here under the tank - not the shut off tap

Forgot to add this . its the inertia switch for the pump , you might spot the common earthing point above it , more on this another time
