Fuel Pump Rebuild or Replacement options for 308 and 512BB

Good evening Everyone,

I was curious as to what others are doing in regards to dealing with cranky electric fuel pump(s) on their 308s or BBs (they use the same fuel pumps, but the BB uses two of them)? I ask, because the original pumps are NLA and have been superceded to what looks like an aftermarket pump. Ferrari's part number of this new pump is 100245 (110 GBP) and some investigation reveals this to be a Facet 476087 ($80 USD) fuel pump (I am 99% sure). The Facet pump is similar to the original, but is different with regards to the inlet and outlet port positions (not really a big deal). Is it possible to rebuild the original pumps and if so, where does one obtain a rebuild kit. I am only considering the rebuild, as I would like to maintain the use of the original components if possible.

What have others done? Any thoughts?

Cheers,

Sam

 

Good day Russ,

Thanks for the info! It is interesting that both of the Mike's recommendation is for Pierburg pump...Fastradio (another BB owner) also likes the Pierburg pumps as well!

Cheers,

Sam

 

Good day Randy and Steve,

Thanks for the info on this!

Randy, I took a look at the available Carter pumps, but sadly there does not seem to be a model 4311 anymore. There is one (or two) Carter's that will work with the difference being the inlet/outlet orientations (and sizes) as compared to the OEMs. Are your Carter pumps look like the following, or are they different altogether?

Steve, is this the style/model of Carter pump you were referring to?

Cheers,

Good day Scott,

Is your car fuel injected? I am assuming so given the year. If this is the case, then the fuel pump you have is quite different than on the carb models (carb fuel pumps have much less pressure requirements). Sadly, the only Bosch fuel pumps I could find were only for fuel injected cars.

Cheers,

Sam

 

Good day Randy,

Thanks for the correction! Did you use one or two of these pumps? Also, how do you find the noise from them (same as OEM, louder, or quieter)?

Cheers,

Sam

 

Good day Martin,

Thanks for the feedback on the Facet pumps and their noise level!

Cheers,

Sam

 

Good day Randy,

Thanks again for the info and the feedback!

Good day All,

This is just a follow up to let everyone know what I decided to do... After reviewing various fuel pump alternatives, I decided to go with dual Pierburg pumps. Although there were many options that would have worked (Facet, Carter, Holley, etc) I decided on the dual Pierburg's for several reasons:

1. Low Pressure Pierburg pumps are/were used a lot with Weber carbs and so they have a history of working properly with them. Webers are very sensitive to float levels and so knowing that these pumps have worked very well with Webers is a good thing

2. As stated by snj5 (Russ) and fastradio (David), there are several noted Ferrari heavyweights that recommend the Pierburg pumps.

3. Pierburg is an OEM manufacturer for Bosch, which in itself speaks to their quality

4. Minor (I hope) mounting changes are needed with these pumps. Although I will know this for sure when I actually install them

5. I wanted to have a dual pump setup to allow for redundancy in case one should ever fail (limp home mode as it were). However, the failure rate of a pump is pretty small and so this point is minor.

As for cost, the Pierburgs are not that much different in price. In the US they can be found for about $80US:

and in Canada I found them online for $100 CAN:

In my case I found them locally for $119CAN and went this route, as I could get them immediately.

Thanks to all for the postings, feedback, and insight!

If I get a chance, I will post pics of my completed installation.

Cheers,

Sam
