I just bought the Centerline Part #FP261 "Fuel Pump Bosch Replacement" for my 1974 Alfa Spider with Spica. I went to install it yesterday to replace my existing pump.
The new pump is too thin for the existing bracket by about 3/4". The hoses are in the wrong place. It looks like the larger hose from the gas tank would need to be cut down. It looks like a new thinner hose to pump towards the engine would be needed.
I had to put everything back together again.
Do you have a recommended install guide for this pump or is there another pump I should be using? If you have an install guide, please supply all info including adapters and hose sizes and lengths needed. Thanks.
Follow up: I was able to replace my 42 year old 1974 Spider SPICA fuel pump with the thinner Centerline FP261 Bosch pump. Here's what I needed:
- 2 feet of 7.5mm fuel hose (Centerline sells this)
- a piece of 4.8mm rubber to wrap around the pump to make it fit in the clamp.
- a piece of 8.8mm rubber with 2 holes drilled in it to put between the pump clamp and the vibration bracket on the car.
This last piece of rubber spacing was needed because the vibration bracket had a screw that was long enough to interfere with the new pump.
The rubber I used came from gym flooring samples I had lying around. Supposedly, radiator hoses work too. You may have to double up.
Note that the electrical screw studs on the fuel pump are 2 different sizes. The supplied electrical connectors are 2 different sizes to match the 2 different screws. This is important when you are crimping on the electrical connectors to the wires. I had a 50% chance of getting right and didn't... ;-)
From my experience I suggest you keep an eye on your newly installed pump.
Many years ago, I, like you chose to use a resilient material between an undersize replacement pump and the original hoop. About six months later I was changing the fuel filter on this car and noticed that the resilient material was mostly gone and the pumps was being held in place by the tubing attached to it. Curious as to how this might have happened, I started the car and saw that the pump I installed vibrated ever so slightly when it was on, but enough so that over time and many miles its movements tore apart the material. It was so long ago but I think the material was a used piece of butyl rubber that I found in the shop. Since then I've been installing replacement pumps using new hoop that I make to fit the replacement pump. I also place low durometer Viton between a pump and the hoops. For me it is mostly about not having to do a job twice.
Of course I don't know what you used, and I don't know to what extent you pump vibrates nor the frequency of those vibrations, so maybe everything will be fine. But for me in this instance my quick and dirty didn't work.
