Sprint Veloce Fuel pump almost final fix

I have this approach I’ve noticed when faced with a job I don’t necessarily want to do on one of my cars, it’s called procrastination, you might have heard of it.  As necessity is the mother of invention it is just as strongly the enemy of procrastination and I it took me having two unavoidable reasons and a little good luck to effect an almost final fix for this fuel pump issue.  The first good reason was the need to give Kip back his SU fuel pump that was given temporary duties on the SV (I was going to see him on Sunday at a shop warming party), the second is the requested attendance of this car at Pixar’s Motorama this Friday afternoon.  The little bit of good luck was a friend having a new Facet fuel pump kit bought specifically for a weber equipped Giulietta Spider that was no longer in his life.  With no good rationalization left to enable procrastinate, I went to my shop yesterday determined to mount, plumb and wire the new fuel pump.

Nice new Facet fuel pump hanging out with 50 years of scummy crud on the underside of the Sprint Veloce.  Note shock isolation mounts, like little motor mounts, and grounding wire.

The Facet fuel pump kit is available from the usual Alfa parts suppliers who shall remain nameless until they at least give me a discount in exchange for a deserved favorable mention or want to place an ad on my site.  The kit includes the pump, a made-in-the-USA Facet pump that physically looks like the original Bendix pump that Alfa Giulietta Veloce’s used, two 90-degree brass fittings and a pair of rubber mounts.  Not included but recommended is a shut-off pressure switch that should be plumbed into the oil pressure gauge feed line. 

The thinking behind the shut-off switch is that if you roll your car you don’t want the fuel pump to continue pumping raw gas all over the place, especially if the car is on fire.  If the car is upside down with the engine running, or if the engine dies there is no oil pressure and the shut-off switch goes to ‘off’ and the pump loses power and stops pumping fuel. My red Sprint has an oil-pressure based shut-off switch and it has never given any problems and luckily I’ve never had to depend on it.

First step was preparing the pump.  I installed the two elbow fitting with some liquid teflon tape stuff that is probably officially called ‘pipe thread sealant’ by a company that makes a lot of high quality automotive goo’s that come in small tubes.  I made sure to try and point the fitting openings toward the destination of the lines that were going to be hooked up to them.  Next I crimped on a female bullet connector with a clear plastic insulating sheath that came in a kit I bought on eBay to use when wiring up a 1963 Honda CB77 Superhawk I had a few years back.  I made up a short wire with an eyelet connector at either end to use as a ground strap.  The last step was installing the two rubber mounts and the ground to the pump body.  I used a pair of stainless nuts and split lock washers for this.

Second step was preparing the car to receive the pump.  I disconnected the battery, jacked it up, put two jack stands under it so I wouldn’t get crushed if something failed, and removed the rear wheel. I crimped a male bullet connector on to the wire from the fuse box, wire-brushed the metal on the bracket where the ground was going to be hooked up and bolted the pump into place.  I had to get under the car to wrestle the fuel lines onto the fittings and got some gear oil in my hair-yuck!  While under there I secured the fuel lines, wires and some other stuff that was hanging down as well as I could, but noted a future effort is needed to make it all happy.

The installation took about an hour from changing into my grubby clothes to torquing the lug-nuts and test firing the car.

Elbow fitting can be seen in this picture pointing back to the gas tank.  Lower fitting is fuel in, upper fitting is fuel out.  I know, what the heck is the big black wire doing going through the spring?  A day spent under there securing all the wires and lines to the body is my next task on this car to procrastinate about doing.

Here’s the stock mount on the body that is intended for the pump.  I’m not sure if standard Sprint’s have this bracket.  Since the pump is rubber mounted I had to run a ground from the pump bracket to the body bracket to complete the circuit.

Next installment will chronicle the installation of the fuel pump power shut-off switch.  Stay tuned!  Future efforts against procrastination will include mounting new seats in the red Sprint, cleaning up the engine compartment on the red Sprint and cleaning up the rear brake on the Triumph.
