I have a new set of KW lowering springs, no coilovers. 2" drop, supposedly made for the M42 cars.
I don't have a lot of personal experience cleaning automobile gas tanks, but if you search the net for something to the effect of "cleaning varnish from gas tanks" you'll get a ton of hits.
A couple of things to consider about the gas tank in our car: The drain plug on the tank isn't very large and there is a crossover tube between the two tank sections. Depending on the amount of debris and rust you have may determine whether or not you have to drop the tank.
I've tried out chelating rust treatments like Evaporust. They work well, but I'd bet twelve gallons or so would get pretty expensive. It also has trouble with fuel varnish.
I've lined motorcycle fuel tanks with Kreem, but that'd be pricey too. POR-15 has a great motorcycle kit, but I'm not sure how well it would work in larger tank. You'd still have to drop the tank to do it right.
New tanks aren't all that expensive compared to etching and re-lining one. Here's one for $228. I'm not recommending that tank nor vendor, just found it with a quick search. You'd still need the connector piece.
If you're close to PA I have a brand new OEM 55L fuel tank, in a box, in my garage, with the connector piece and o-ring...
Okay thanks. Unfortunately I live on an island and I've been to every auto store down here and can not find the 4 pin orange bosch one. No one even has an off brand to match it up.. I will take out the fog light one and give that a try thanks for that
I can send you one for the price of postage. Let me know.
The fuel pump relay is just a normal 4-pin Bosch 30amp relay. You can find compatible relays at most auto stores. The orange Bosch relay is optimal (has some voltage protection resistors IIRC) but for a temporary fix you can use any 4-pin relay. If it has four terminals marked 30, 85, 86, and 87 it'll work.
The wiper or fog light relay in the fuse box is good for a roadside quick fix. The main relay has five pins, they're a bit harder to find.
Just an observation...although I am having troubles with my e30 318is...it will start and idle. If I disconnect my AFM it shuts down immediately. Granted, you might have fuel pump issues...based on my observation I am willing to bet you won't get it started without the AFM in place. Just my .02 worth. Good luck.
You're welcome. If it turns out to be a bad pump you'll have to pull the sensor out first in order to pull the rest of the assembly.
Heres a picture of how i wired the fuel pump directly to the battery
That's your fuel level sensor. Pull the other connector and with the key turned to "On" check for power: pin 2 (green/violet) is hot, pin 1 (brown) is ground.
