Just for confirmation, I have been reading a lot that a 255 is too much flow for stock fpr, yada yada. Well, I had a 255 walbro for probably 3-4 months on my is no worries, then I had swapped it to my friends eta and its been on that for a few months as well. No issues at all.
Good mod, and pretty cheap.

Everyone talks about dumping the dual pump setup on early models, but is it going to be an issue to install a TRE pump instead of the external pump and keep the in-tank pump?Originally posted by priapismMy girl don't know shit, but she bakes a mean cupcake.Originally posted by shamesonUsually it's best not to know how much money you have into your e30

Lots of people mention this being easy, but this is turning out to be more of a pain than dropping the m50 in my e30... First of all the fuel pump that has a return line on it requires a lot more modification to get it to work, Did all that installed it. Ran great for about 30 seconds till i put a load on it. im not sure how to explain what happened. Now the car will not even start and it looks like my return line is clogged and was leaking into my engine bay. Due to the amount of modification to the initial bracket I can no longer even put the original pump back in.
What a pain in the ass.

The original feed line i had from the pump to the metal line burst, so i had to replace it with something a little sturdier.. In the end the car runs very nicely. I get no power loss that I had with my old fuel pump not sending enough fuel. Note that this is EASIER if you dont have a return line on your bracket!!!

i fitted one of these pumps to my 318is, it runs great but the pump is actaully resting on the bottom of the tank and causing a vibration/hum noise throughout the car, its pretty annoying but if i cant fix that problem im willing to put up with it since its better then having a non running car

My car is an early production 87 325i convertible. I am in the process of doing the single walbro upgrade but im not sure how to wire it up. My stock pump had 1 wire coming off from the plug. The ground is through the the metal piping with a metal (strap) going to the pump. How can i get 2 leads from the plug without causing a leak. Should i drill out the stock plug and epoxy a newer plug in? I just don't want to break the metal piping.I need your obd1 parts! Harness intake ecu etc.

I did this yesterday after my pump died. After I made the little foot to hold the pump in place I noticed that the pipe I bent (closed off) was a return line. Drilled a hole in the bottom and it all worked out. Only problem I had was one of the fuel senders nuts is stuck and wouldn't unscrew after putting it back in... any idea on how to break it off if I need to access the pump again?sigpic
