I'd like to get a hydramat on my setup. I've hit fuel cut a few times.

The combination of the hydramat and the return line focused over top of the mat that makes the difference. Like I stated before, when I tested it I literally ran it down to fumes without cut out.

Exactly this and why they are being sold a "normal" filter is beyond me which doesn't really make sense as the need for a venturi was a must back when this fuel started in 2013-2014? What has changed absolutely nothing! If anything there should be a bigger push for these mats as these cars are being bought by a variety of clientele some with plenty of experience and some with very little.

We can modify your (fuel it) bucket get ya a hydramat = no more fuel cut! But if you're bucket-less send it to me I'm sure I can make a custom clip to make it work to accept the fpr lines - for free

So I'm understanding that there is some fuel line modification that needs to be done I'd assume to remove the bottle neck in the factory push lock hard line.
Could one of you guys post up some pictures of what exactly you did and know that is reliable when you get a chance?

Thanks in advance!

Thanks, I'll wait for him to post up :)
I have a complete DIY for the installation including the Hobbs switch. Unfortunately I used photobucket to host the pics so I am having to go back and re-do all of them again. I'm on vaca right now in Asia so I don't have access to everything but I'm going to try to work with what I have.

As for the push lock, I simply heating the end of the line where it connects to the push lock. Once it was nice and warm, I pulled the push lock out and inserted one end of the "y" tee that Jose supplies. Then I used a clamp to tighten everything down between the tee and the feed line. You could also just cut the push lock out and secure it all with a clamp. Either way its a 5 min job and its been working perfectly.

I'm gonna be running e50 so I'll be going with a single not a double 450

Dont know if that changes anything...

maybe I missed it but how did you delete the venturi but still get fuel over from the other saddle tank?

No problem, there are 2 lines that come from the other side that all oem buckets have clips for. I retain the use of the bucket for that purpose to retain those clips for those lines to dump fuel onto the mats. Some kits have gone bucketless with just the walbro filter which is dangerous and can lead to starvation(as some have told me they have experienced) which can lead to lean conditions. Lean is mean until it pops one of your pistons.

My pump is actually put together by a local guy, I'm alright for now until I work on the other side of my fueling. Thank you for that, I'll keep it in mind.
