Estate / Van intank fuel pump Ideas ?

[Savvi]

I fitted Pinto injection manifold etc. onto my MK1 van some time ago, then realised i could have problems with the fuel pump side of things

 

 

So i parked it up was doing other bits as well and a little while ago had an idea after fitting a new in-tank pump for a customer

 

After a bit of searching i realised a Citreon Saxo pump and guage could easily be adapted to fit into the van tank and managed to find one for £20 this week at the local breakers.

 

 

It has the same depth and also has a built in sender for the fuel guage.

 

I marked the hole and cut it out then filed it out so the rubber seal is a nice tight fit !!!

 

I just need to make a bracket or locking tab to hold it all togeather.

 

 

I've not fitted the spare tank yet but i can't see any reason it shouldn't work, also the pump has a built in swirl pot so i shouldn't get any problems when cornering etc.

Excellent Looks made for it

Thanks

 

 

I'm open to some suggestions on securing it in the tank.

 

Really don't fancy trying to spot weld some studs on it, although i think that would be an ideal solution

 

 

Was told today if you connect a car exhaust pipe to it and leave the car running for an hour it's then safe to weld ?

 

I'd prefer someone else to try that before me

[Savvi]

Does anyone have an idea of securing the pump in the tank ?

 

 

Or is there a safe way of welding some studs in without it blowing up !!!

Ive heard that filling the tank with water works. Makes sense really because if its filled with water then there can't be any room for leftover petrol fumes.

 

What about using nuts and bolts through the tank rather than welding in studs. Then seal them with solder or petropatch etc?

[Savvi]

Someone suggest riv nuts, which i think should work ok, perhaps with a dowty washer ?

[emu]

can you get blind ones? that would work well I would have thought.

 

I'm liking the whole 'modern pump/swirl pot' idea too It's a very neat solution.

[Savvi]

i'll look for some blind ones

 

 

 

Yea i didn't want 2 x pumps swirl pots etc, as i wanted to use the van, i'd changed a few of these type of pump and thought if i could find a smaller one it would be a better job

Riv-nuts are OK but stick up a little, so the gasket would need to be quite thick I think.

 

I've welded a petrol tank before though, we just made sure it was thoroughly clean using something like brake cleaner, and then double checked to make sure it was dry. Didn't have any problems

How about using six self tappers? If the petrol tank steel isn't rusty they should do the trick, just make sure you drill the holes in the sender unit slightly bigger than the screws. If it doesn't work you can always drill the holes bigger and tack some studs in instead! I once welded up a hole in a bike petrol tank and swilled it out with diesel first, seemed to do the trick!

Sorted ............

 

 

I used rivnuts didn't matter about sticking up as the flange and rubber gasket took up the slack.

 

 

I pressure washed the tank and filled it, turned it upside down and it only leaked out of the breather So hopefully it should be ok.

 

Cleaned the tank off going to give it a coat of paint and fit it in to see if it all works !!
