dryheat Posted November 20, 2009 Report Share Posted November 20, 2009 I am looking to modify my stock 71 wagon fuel tank to install an in-tank fuel pump for my fuel injection project. I picked up an extra tank and started doing some measurements and determined fairly quickly that the top of the tank isn Quote Link to comment
imtb Posted November 20, 2009 Report Share Posted November 20, 2009 Post some pics when you get to installing the fuel pump. I have an extra tank and was wanting to do the same thing. mikee Quote Link to comment
WagDatto Posted November 20, 2009 Report Share Posted November 20, 2009 That's the same problem I ran into when I swapped in the KA. I ended up scrapping the old tank and making a fuel cell. If I had to do it all over again, I'd just use an in-line fuel pump. It would be AGES easier! Quote Link to comment

dryheat Posted November 20, 2009 Author Report Share Posted November 20, 2009 thanks guys ... in-line with a swirl pot and low pressure pickup pump ... or just in-line straight from the existing tank pickup and add a return line? Quote Link to comment

WagDatto Posted November 21, 2009 Report Share Posted November 21, 2009 With the stock tank, I doubt you'd have any issues with fuel starvation. At the very least, you can install a sink on the end of the pickup tube (small weight that rolls with the fuel so it's always there to suck up fluid for you), but it should be find just dipped down into the bottom of the tank. With my fuel cell, I'll eventually be doing a "swirl pot" with a low feed pump and an in-line 255lph, but for now unless I'm low on gas, I have no issues. Quote Link to comment
greybeard Posted November 30, 2009 Report Share Posted November 30, 2009 if you use the stock tank with FI you will need some sort of accumulator tank in the system. or the vehicle will have starvation problems with less than 1/4 tank of fuel. I've changed a carb. RX-7 over to FI turbo and helped a friend with a fuel injected 240Z and both had fuel feed issues at about 1/4 tank. for the RX-7 a tank from a FI tank(GSL-SE) has a baffle inside that solves the problem. for the Z an intank feed pump and small accumulator/ fuel pump set up (87 VW Jetta) solved that problem.
