Does anybody have a link to a photograph / illustration of the best location for an electric fuel pump? The only photograph I have been able to find here is one mounted in the engine bay - but with several other pople saying that engine bay is a bad idea because of fire risk - which is what I had understood. So could somebody show me how they did theirs please? I have a 2-llt, type 4 (CJ) engine.
I have had a Huco electric pump mounted to the firewall for a few years and it has been fine. Not a fire risk so long as you have a cut off valve in the line to it from the tank. I am however going to switch to a Carter inline pump mainly for reliability as it’s a rotary type. I will be mounting this underneath probably on the chassis rail.
mine's a huco too, also mounted in the engine bay, also a 2.0 CJ (i always want to say "I didn't get where i am today.." when i say that.. youngsters you may need to google that) also have a cut off and a plumbed in fire extinguisher which will cut the power to the pump if it's triggered.. and new fuel lines yada yada. if its in the engine bay you are more likely to see if it's started to leak vs something hidden underneath but i totally get the counter arguments. btw - i'm also rob, and i also live in oxford. are you copying me?
I was thinking something like this position .. self-tapping screws? (Obviously not the tie-wraps as show, this is just for the picture):
Similar to mine. Offside rail, directly under tank outlet, with pre pump filter. Sent from my SM-N970F using Tapatalk
I wasn't aware that I was copying you. Maybe it is a glitch in the matrix? Although I notice that your bus is the wrong colour
@jim mcglynn : Thank you - mine looks about right then. @Gooders : Ahh .. so I DON'T have an inline fuel shut-off valve before the pump Is that instead of using a relay to switch off the pump when the engine stops .. or in addition? Do you know a good in-line fuel cut-off solenoid?
25 years, 5 bays, never had a fuel cut-off solenoid or an engine bay fire extinguisher or a fire. If it goes up in a ball of flames I'll claim on my insurance... but it's no more likely to do that than any other old car IMO.
Even my engine fire was during maintenance rather than out on the road. But the cut off solenoid made sure that once the initial fuel caught, all that fed the fire was the plastic dripping off the wiring harness and the LED lighting strip.. Some fuel pump designs may be more or less likely to allow fuel to flow through when they are switched off - some have non-return valves that need pressure to actually open them which is higher than the steady head of pressure from the tank, or the rotor of a rotary pump will only let through a trickle of fuel if it is stopped.
Here's my setup, mounts on a bracket that goes on the gearbox, inline shutoff and all connected to fire extinguisher Sent from my SM-G975F using Tapatalk
I have a fuel cut off crash sensor feeding the huco fuel pump under the tank feeding a filter king bolted to a panel fitted alongside the wheel well in the engine bay. All seems well with it.
Folks! Amazing responses above - thank you! @Milo-steel .. I think you set the bar high here ., looks like I have my work cut out. Thanks again!
It’s the fire triangle thing Fuel Air Heat make sure your hoses are ok and on tight no worries, Like Zeddle said make sure it’s insured, If it goes on fire it’s probably down to negligence anyway
I like a solenoid so that the crank case doesn't fill with petrol when I have a leaky needle valve in my Weber IDFs, and they don't last long. I use a 12 quid job off eBay, you can just see the green bit of it in this pic I then took the fuel pipe across and mounted my rotary pump and filter on the sloping bit and then took the pipe into the engine bay via the bottom n/s corner Hope that helps. It was easier for me as I was starting with a blank canvass and putting literally everything in new. But if you can get access, it seemed like a good option to me.
Plus one for the engine bay, easier access, easier to change, if it goes wrong and easier to check on. Keep a spare on the Bus. It was done by the previous owner, but I could move it easily enough. I installed a fuel cut off solenoid triggered by a timed relay so fuel only runs when the engine does, I put fire extinguisher in the engine bay as my second job on the Bus. I perfectly understand the counter arguments to fuel pump location.
