Hi

The other 2 were like a big self tapper, all 3 heads were rusty, but this one wont budge

Is that a bit of the bolt sticking upwards or do the bolts project into the tank?

Cant quite picture it - even though theres a picture - if you know what i mean!

Hi Geoff

Thats the bolt after the head snapped off

Theres about an inch of bolt that still needs to come out

How about heating the end of the bolt with a soldering iron and trying to pull it out?

drill it and heli coil it.....I swear by them..

Tried heating it with soldering iron, but mines quite low powered and it didn't get it very hot

how do i drill a steel bolt out of a plastic tank?

Grind the top flat, support it from underneath and centrepunch it. Then start with progressively larger bits till you get to the thread and you may then be able to peel it out with snipe nose pliers or tap what's left out. The heat from drilling may work it loose if you're lucky.

Hi Pete

Because the bolts a self tapper, its shank is only 3mm thick, wish i'd left the rust bolts in now

Hi Paul

Oooooh - could you give some rough dimensions for it?

Cheers

liam

um... good luck with the bolt

That sounds usefull as i am planning a megasquirt conversion during the winter, Ill keep my eyes open for one.Just have to decide what engine to use , i have a crossflow fitted and a blade engine that I was going to fit, but am tempted by a 160 +hp zetec which should be easy to achieve .

How about filling the tank with boiling water? and then a good pair of molegrips on the bolt.

Thanks for the tips on the bolt, still stuck though

For those interested in the golf fuel pump, theres a few on ebay

I havn't been able to find specs on the pumps flow and pressure ratings, but i'm hoping it will work ok on a 150bhp pinto

Adrian

It should work no problem. The std mechanical fuel pump is supposed to be almost man enough for 150bhp so high pressure pump should be good.
You may need to think about a fuel pressure regulator. I got one for £25ish with adjustable dial (im running 38DGAS and had facet red top in stock so will be regulating it down quite a bit - plenty in reserve for future upgrades.)
