Fuel pump question

[klampy]

Hi guys. Iv got a VS super6 fuel pump that iv put into my VRs fuel sender, iv just been told i can use a pump (meant for internal mounting) externally. i always thought it was meant to be immersed in fuel to keep it cool but he says as long as theres fuel flowing through that it will keep itself cool. and since its only going to be a lift pump its not going to be under anywere near the pressure it otherwise would have been.

so basically, can i use an internal pump externally with no worries of it over heating?

Besides the over heating issue you might have, how will you manage to clamp a home onto it? There isn't much of a lip on the pump... Give it a go, you can pick one up from the wreckers for about 30 bucks so no biggy if it goes bang!

[klampy]

so will it over heat? thats my biggest question at this point in time. i can sort out fittings n stuff later on..

[304runner]

Im not too sure mate, but if I had to give an answer, id say it would over heat eventually...

[delcowizzid]

will get hot its made to be submerged why would you take it out of the tank anyway it fits perfectly

[klampy]

so how many commodores get around with the fuel light on? the pumps usually exposed and out of the fuel level in that scenario. pump failure doesnt seem "that" common. or is it more common than i realise coz it hasnt happened to me?

so perhaps i should just try it hey. get a sumped fuel tank n mount my pump to it n see how long it stays cool for.

im not using the standard tank is why.

[klampy]

basically, just not keeping the standard tank under the car because of how low it is so i want something inside the boot. and the stock tank is too bulky to really go inside so unless i mount the original fuel sender into the side of a square tank ill have to settle for a universal tank and i figured if i can use the pump iv got then it saves me having to buy another pump.
hence the question of wether or not the intank pump would overheat if not submersed in fluid. and a fellow i know who does all round performance work to a range of cars says that it wont overheat and so i wanted a wider field to ask.

so mike your saying it WILL overheat if not submersed?

[delcowizzid]

the swirl pot is allways full so it keeps the pump cold they do wear out quite fast if you drive them low all the time .if you are going to build a tank with a sump you may as well just use an 044 external and be done with it

[klampy]

youve just given me some ideas.

if a stock tank had been empty for about two years and been washed out with water numerous times will cutting into it with a grinder ignite it or will any vapours be gone by now?

[delcowizzid]

dont cut it it will still explode LOL

[klampy]

is there any way i can cut the ends off without it going bang?

[delcowizzid]

tinsnips LOL .stop thinking LOL why go all complicated intank pump into surge into 044 done and dusted

[klampy]

thats exactly what i want to do. its not complicated! lol. but the tank i have is too big, i want to cut it down and re-panel the ends. hell of a lot cheaper than a $200 fuel cell. thats why i want to know how to cut it without blowing up lol. its been outside empty for at least two years, surely any vapours would be gone by now?

[redvs2]

Drop a match in and find out

[klampy]

well! its worth a shot ay? ill get someone i dont like to do it just incase. lol....

[Dr HaxZaw]

if its been sitting there for 2 years i dont see how cutting it would be a problem as long as its been breathing without feul in it
if your worried fil it up with water and just cut it with the angle grinder

although to be honest wouldnt it just be easier to make a new one up?

[304runner]

No...lol.... it wouldnt blow up.. If your worried fill it up with water first and it will expel the fumes (if any) then drain it and cut it...

[klampy]

ok sounds good. id draw a pic of what im going to do but at work i dont have ms paint or anything... basically i just want to narrow it down. and i figure while iv got it open ill also weld some baffles in. and the new end plates will also become feet for the tank to mount to the floor with. pretty straight forward, nothing fancy. and also ill be welding in the old filler neck to the top or side of the tank as ill be removing the old filler from the end ill be cutting off which will allow me to keep the vent. so a couple sections of 1-1.5mm steel will be fairly cheap. especially compared to me buying a new fuel cell. and this way ill be still able to use the original sender unit/pump mount keeping the pump submerged and no worries about having to sort out a feed tube.

problem sorted.

now i just have to do it.

[HIROLLA]

why not use a fuel cell?

[klampy]

you wanna buy me one? For ten bucks worth of steel and a small amount of effort i can have exactly what i want.

For 250+ i can get something thats right for the job but not what i want.

I know what id rather do.
