TR4/4A Electric Fuel Pump for TR4

[Deleted member 7471]

After reading about some of the woes and risks of stock mechanical fuel pumps, I am considering a change over to electric for my TR4-A. Does someone have recommendations?
Will the Facet 40105 work or does it deliver too much pressure? I am running SU HS6's, engine is stock.
Thanks

After reading about some of the woes and risks of stock mechanical fuel pumps...

We read every day of car crashes... and yet we still drive.

In other words, perhaps the fuel pump problems you read about here should be taken in the context of all the TRs that are not having said problems (and do not get written about).

I won't claim that the 4-cylinder pump is bullet-proof but as mechanical devices go they seem to be fairly reliable.

If it ain't broke don't fix it.

And Crypty IS broke !

Seriously, Glenn, don't go inviting more trouble than you already have.

Yes, Facet 40105 is the correct pressure range. I liked the idea someone had of keeping it in the trunk as a spare and then just hotwiring it and swapping it in place of the mechanical pump if needed in an emergency.

That said, if you have the original pump, the diaphragms are readily available, and if they are old (or you don't know how old they are) why don't you just order a new one and swap it out before it dies? The diaphragm / valves (which are both part of the rebuild kit) are the only parts that wear out. For the rather minimal cost of the kit, and very little time needed to install, it seems to me that it is easier to do the preventive maintenance and forgetting about this for the next few years.

...very little time needed to install

In fact can't one rebuild the TR3/4 pump w/o removing it from the engine? i.e. remove the 6 or so screws holding the upper half in place & lift it away, then replace the diapraghm & valves.

I *think* I have done this but maybe I just dreamed about it.
