hey cuzz33 just a quick word on the monobloc situation.

Firstly go back and read everything djhatton has said as its right on the money. Power ratings on speakers and subs mean very close to nothing and depend on box type and size and a lot of other factors as well as being stupidly inflated and generally pointless.

I know you said you already got a box but don't think you mentioned if it was sealed or ported but anyway i'll leave the amp power choice up to you but whatever you buy make sure you check the THD or total harmonic distortion ratings to make sure the amp can operate at the given ratings without sounding shit or blowing your gear up. If you can't get hold of THD ratings or if they are above 0.5% then you may want to think twice, if they are above 1% then turn around and run away. A really sweet monobloc will stay close to or at 0.1% at its rated power but even 0.2 or 0.3% should still be fine if you've got enough power, and like djhatton said you can never ave too much clean power (rated in rms of course)

You said from the offset that start that you were after a monobloc amp but most monoblocs are made to work at their best at two ohms impedance, your sub is four ohms so the same amp will be making right on half the amount of power as it would be at two ohms.

The other option for making some decent power to a four ohm sub is to get a two channel and bridge the two channels. When hooked up to your four ohm sub both channels will be working at two ohms to create total resistance of four anyway so you'll be getting good power for your money and a heap more power than twice what each channel will run by itself.

Something to look into anyway

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
