EOSpeed Billet Fuel System Installation

[NoGuru]

How has this been doing since install? I believe my ekp is dying after putting in my 535. I can get one log in and the my rail pressure tanks. Not the normal not enough flow pressure drop, it is a straight line drop to 55psi. Car won’t start for five minutes then cruises around town fine. Which is the ekp cooling I think.

so I am looking at the bpm4. But I hear it can melt the top hat? Also not reassuring that I am about to spend $700 and cant get a hold of anyone at EOS. Am I stuck between choosing a stock replacement from fcp that may die quickly or risking burning my car down?

I have never heard of it melting the tophat. Where did you read this? I don't even see how it could.

I've had the BPM for unit for quite a few years I think 4 years now and there's been 0 problems with top hat.

Stock turbo with port injection and stage 3 PR LPFP.
Then Pure S2 with same fuel set up.

Thanks for the replies. I guess the increased current can exceed what the stock wiring can handle and melt the connector at the top hat? I don’t remember where I heard it so just want to get your feedback since I am in this current scenario of replacing my ekp.

The top hat issues are with high resistance studs on a secondary pump. Using the OEM connector for one primary pump is fine. Been running a 450 off the BPM4 for quite some time now with no problems. I have the billet top hat ready to go if the second pump is ever needed but should probably just list it up for sale here.

Quick question. Does anyone know what the spring is for on the top hat rods? I see the EOS top hat doesn’t use the spring on the rods. I am going to use the top hat with my diy bucket. Trying to figure out if I need to pull the springs off of my plastic top hat and put them on the billet one or if it’s not necessary.

I would use them. That is what holds the pump tight to the bottom of the tank.

I have a few additional questions I was hoping someone could answer please. I am probably overthinking some of this but I can’t help it.

1. I see some heat shrink used for wiring that will come in contact with fuel, is there a special brand you use that is compatible with fuel?

2. There are two more sets of wires that go to the plug to power additional fuel pumps. I can see you put heat shrink on the unused wires sitting on the top hat. Did you put heat shrink on the unused wires that are sitting in the tank?

Thanks,
Houtan

As far as I know, there is no Fuel specific Heat Shrink. Just make sure it is of good quality. You don't want one strand to get out and arch to cause a spark.

Any time I have unused wires that I leave in a system, I cap them with Heat Shrink.

I had my top hat melt on the second pump, these new top hats will stop that from ever happening especially when running bigger pumps.

actually not all heat shrink that can handle gasoline... ive had a few that unshrinked itself...luckily it didnt short circuit and blow stuff up
i ended up buying ptfe based heatshrink that works fine

 

[houtan]

So I am seeing most heat shrink is made from polyolefin. Which is not fuel compatible. @doublespaces , did you use a specific brand?

I reached out to EOS and they told me to buy DR25 heat shrink.

So this is what I purchased: https://prowireusa.com/c-27-raychem-dr-25-.aspx

It is a milspec grade heat shrink.

Raychem makes top notch wiring products. They’re the standard in motor sports. You won’t be disappointed.
