That plastic straw hose stuff is junk IMO, I've seen a few instances of it breaking, get the rubber submersible fuel injection hose that is ethanol-safe. It should be around $15/foot...

FWIW I've been running the hose that came with my MAP kit for about a year and a half on e85, no problems. When I first installed it I thought I had kinked it (see my project thread) so I took it back out and rearranged it, no issues thus far, even after upgrading to a w400!

The problem is that a straight hose gets kinked, I tried this. You have to get the 'S' shaped hose that comes in the cobb pump kit (or one like it) if you wanna run this type of hose.

Nope, I've been running straight hose for a year and a half, it's fine if routed properly. Cobb no longer uses the S hose.

Thanks guys!

I had read about the routing issue before I did mine and made sure it was routed down and back out with no kinks, etc. It was not a kink issue for sure. It is flared out where it broke as if the line was getting weaker or something was caught in it backing it up and it exploded.

I did talk to MAP, and they said the line is definitely used by a lot of guys for e85 and working fine as e85 is the main reason most people upgrade the pump / buy that kit anyway. But... read on.

I replaced the clear line with Gates 27093 ($28 for a foot of it at NAPA, they had it in stock at the distribution center one in St Louis Park). It is tricky to route such that it won't be kinked once the bucket's bolted into the tank, but definitely doable. After that, car started right up and ran good... for about 19 miles of a 21 mile drive home.

It died again, clearly losing fuel. Still had tools/etc in the car of course, didn't even put the back seat back in, so I pull the bucket out again, turns out the DW300 died. Luckily I still had a DW65c at home in the stock hanger assembly, so my wife brought it to me and I swapped it in.

Sounds like the 300s have a bit of a reputation for dying, then sometimes working 20 minutes later, then dying again. Probably a combination of the stop and go traffic, hardwire, and inadequate return line system... so that's the end of the 300.
