Does The Fuel Tank Need To Be Near Empty For Pump Replacement?

Let me put it this way. I wouldn't want the tank to catch on fire whether it's 'full' or 'empty'. Even when it's 'empty', I'm assuming that it's not removed, tipped upside down and drained, so it probably still contains 15 or so litres. I'd hate to light thtat on fire to see how it goes. Won't be pretty - enclosed space.

All that I can say, is when I work on cars, I don't have the luxury to have cars empty. sometimes they're full. When I installed the pump into my own car, I did it full - like I said, no problems. I just be careful. Battery is disconnected, and I don't go around sparking things!

Oh, I also have a fire extinguisher in my workshop

That could be true too. When my friend was drunk, he tried to blow up a fuel can by dropping a match inside. It wouldn't light. All that would happen is everynow and then, some of the vapour above the hole would flash, but nothign inside

a full tank is less explosive than an empty tank, however in this car it wouldn't be that much different because the vapour is coming out of the tank. a full tank that had a spark ignite in the boot would burn for much longer, but it might not explode as big.

i did it with an empty tank, but i would've done it with a full tank if the car had had a full tank at the time. the only thing is that i was sticking my arm all the way into the tank to make sure that i got the pump down as low as possible, so i would've had an arm covered in fuel if the tank had been full.

on a side note, the r33 that i installed an 040 into has no issue with surging with under 1/4 tank left. the owner has got it down to the top of the E (so it was uner the empty line) and still had no issue.

also, if you disconect the battery make sure you have the clamps well away from the battery terminals. if they are close and you bump it you may cause a spark. disconnecting the battery isn't always the safest option.

Well I spent over 2 hours on it on sunday before giving up.

The 3 lines took bloody ages to get off they were on so damn tight, then once that was done I spent like 80 minutes with a hammer and a block of wood and i just could NOT get that friggin cap to budge. It then started raining so I went 'f**k it!' and gave up.

And yeah I made sure to move the terminal clamp well away as I know it sparks when it touches. Although to be honest I think I would be passing out from petrol fumes before the fuel vapour got bad enough to ignite.

Also mobile phones causing fuel ignition is a 100% myth, as proven by mythbusters :thumbsup:

Anyway ill just get a shop to do it, least I tried to do it myself I guess. Thanks for the tips guys.

i have done them both empty and full, and imbetween, im glad i did it emptyish first, as it meant i could actually see the bracket. its not hard at all, but being able to see it will make it alot easier first time. take off the battery earth etc, and remember to fix your fuel level sensor while your in there. they seem to always be dodgy in 33's

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      @GTSBoy Yeah i know. The RB20 has 180Nm torque and the gearbox "should" take up to 400Nm if you are not doing stuff like drag/drift or dumping clutch and of course then it is pure "luck" on how will it last. My problem is (i think i said this in different post) that my car was very badly maintain so i would not be suprised if the oil in the gearbox was not changed until i bought it. Yeah the gearbox seem little bit sad.   @Sxnjeet the +T seem very interesting but from where iam from it was nearly "impossible" to done right and not blow twice as money as just swap for the RB25.

      Spray painting interior plastics

      By MBS206 · Posted

      If the plastic wore, the paint will wear quicker. Heck, most car manufacturers cant keep the coatings they put on their buttons/trims alive these days for more than 5 years... A cheap paint won't do it!   However, you can get away with high quality vynil wrap, primarily in areas that won't cop much abuse. Skip colour matching, and just try and wrap a specific area with an edge in a new colour.   PS vynil wrapping is a prick of a job, and I suck at it, even for a small dead flat surface...

      Help Understand GTT Boost Setup

      By MBS206 · Posted

      I think this is more a question you should ask the tuner. My assumption is you have nothing plugged into the original pin for ring gear crankshaft, which is where your map sensor should get wired to, but now you've asked the tuner to disable it. I'm assuming (because I haven't memorised your setup) you are using RB25 ECU on the RB20 loom, to plug into an RB25. You will want to check what else is connected potentially backwards between the engine, loom, and ECU. You might be all fine and safe. The best solution you could have done is wire in a map sensor, and leave the ECU able to read a map sensor.
