I know it's a bit too late, but if your ******* with your fuel tank a whole bunch, I've found it is much easier to just lift the box off than to drop the tank. I do this every time I need to change the fuel pump in one of those trucks.

well today i messed around quite a bit.
had to drop the tank 2 times, chasing what i thought might be wiring issues, but turns out the fuel pumps draw so much they were just making my relay hot, 30A continuous and 40amp peak...
oh well least i have crazy wiring to the tank, brand new fuel filter, the old one was clogged up bad, and i ordered some 70 amp relays...
after doing some reading up these things draw like 16-18 amps at 5bar, 13.5v... crazy!
anyway we drained the tank, wich took forever because the fuel filter was pretty clogged, we took around 25g out of the tank, took about an hour.
once we got the tank out i used a nice Y fitting and modded the basket to hold these big boy 400s.
so, its ready go go when more stuff rolls in, we wanted to start to get the top end of the motor torn down today... that reminds me, i gotta order head gaskets...

yes, i am running twin 400s, seems like i need a bigger relay for them i was just looking up a thing that says they draw nearly 20 amps a piece goddamn, they are beats but my 40amp relay is getting hot, so im gunna get a bigger one for them.
first i thought the wires were too small, rand all new wires and larger connectors, moved grounds, replaced the fuel filter, etc etc, now its still just the relay getting hot lol
wasted all day ******* with it, but oh well.

next time your are at a pull a part yard- grap a fan relay from a late 90's crown vic- its 70amp with the 3/8th spades- pretty beefy and cheap.
all the mustang guys use them on their elec fan rewires.

Im in canada so i might be getting fucked here, but 96$ EACH for a ls9 gasket my cost, regular 135$ list, and 65$ EACH my price for a lq4 gasket. Im gonna put the lq4 gaskets on my junk but was looking for a cheaper route.
