OK, I've just removed, sealed, and replaced a leaky fuel pump on a '93 XJ,
4.0L, H.O. - and I must say that it was not a pleasant experience.
The previous owner never seated the pump against the tank properly and
I had to bend the assembly (a lot!!) in order to get it to fit in the tank.
The solder joint on the OUT and RETURN tubes were cracked and leaking.
The plastic wire grommet was leaking, too.
While I had everything out, I shined a light and inspection mirror in the tank
and found 3 filter socks and 2 of those rubber tips (from the RETURN tube)
floating freely in there. It was real fun getting them out.
The O-ring was a P.I.A. to keep seated while struggling with the pump flange
and mount ring.
After almost a whole day of struggling and breathing in fumes and soaking my gloved hands & shirt with raw fuel, I finally thought I had it all together.
Jump in. Switch on. Engine bursts to life. Fuel gauge reads in reverse.
(...this is really annoying since it was working OK before, and I didn't mess
with the sender wires, at all).
It is my thinking that this setup is for the birds. Also, I'd hate to have to
deal with a kaput internal fuel pump on a roadside emergency (especially if
the tank is half-full or more with fuel).
Has anybody swapped to an externally-mounted pump? I want to keep the
stock sender, and remove the internal pump and extend the pickup tube.
I know that racer-folks use an external pump this when putting in plastic fuel
cells - but I'm thinking of sticking with the stock steel tank.
Shouldn't be too hard, no?
Any pointers? (...better yet, is there an aftermarket kit for this?)
Pump preferences?
Where to mount?
Thanks, y'all.
