Hello,

got the fuel pump in where the carb fan mounts and powered off the coil (im aware neither is ideal but ill fix it after this post) :P

i was going to mount it low down but there isnt any existing bolt holes nor are there any real good positions to bolt it to.

where has everyone mounted theirs? worse case ill just make up a bracket to bolt onto the transmission housing or some such using the existing bolts.. i believe les put up a pic before but its disappeared.

but its working pretty good at the moment! recommended. next to put a relay to switch battery power to it..

cheers

On the later FI cars... the fuel pump is mounted relatively low and the pickup from the tank is also taken low.  Electric pumps are not known for their suction, but for their PUSH... hence many are mounted inside the tanks of new cars...

Secondly, they're usually kinda noisey and will tend to run hot, so mounting them in the tank cures most of that also without any fire danger.

Obviously you are using a mechanical fuel pump tank and just pulling the fuel UP and OVER the top of the tank now negates the advantage for the pump to be mounted low.  The fact that is does pull it up that far is basically proof enough its OK to mount it there.

Heat, noise, and vibration are the only other factors to contend with... and if your side vents are clear and the engine cover is not crushed and vents easily, that cares for the heat.  (I have cut off the mesh from inside the side vents allowing about 30% more air to flow, and also removed the raintray from inside the lid, for heat to escape easily, especially in traffic.)  As for noise, it is what it is and attempting to curtail it would only increase the potential for a heat problem.  Vibration can best be handled with rubber mounts, and hopefully they came with the pump.

Les (lezesig) did indeed build quite a mount that I believe consisted of the pump, a filter, pressure regulator, and pressure guage... but all that is not necessarily needed unless you do interstellar travel as he does...  Looks great though! 

I've personally have run a stock mechanical pump at 3 1/2 pounds pressure for tha last 25 years... and it works great.  I changed it out at about 18 years for a NEW $5.00 pump that was on sale at Bruce's in New Jersey... just because... and kept the old one as a spare sealed in plastic.

Continue having fun... Ya might try paging Les and ask if he'll post a photo again... He does some remarkable work... great "eye-candy"!


My best,

Specifically, the fuel pump on the later models is mounted low in the engine compartment, directly below the fuel tank access point. I'm sure there's room available for you to make a mount on the firewall down there.

As Tony said, it is better that the fuel is delivered at the pump, (hence low) so it is pushed to the carb. (or FI rail) Your resulting pressure is a little better also.

I have both. (FI and carb) The cylindrical pumps are relatively quiet, while the piston pumps can be heard but their low location and rubber mounts make them relatively quiet.

Good luck with it and post us some pic's!
