DOHC fuel lines replaced

Recommended Posts

Finally got around to replacing fuel lines last week as highly advised by Reaper, Turbo, Hemi and others. I used fuel injection rated lines cut to the same length. 

Six short section as fare as I could tell. A couple areas took tight turns and looked like the hose was kinked, particularly back next to the filter where it takes a 180 degree loop back.

I left it thinking it might correct itself with fuel flow under pressure. Took the car out yesterday for a run and it purred nicely, hit the gas a couple times and it slightly hesitates.

Could the hesitation be a result of slightly kinked lines? Just drove it for a half an hour, might the lines correct them self's with a little more time? Any advise is appreciated, THX

The line you replaced to the fuel filter was a specially 'formed' fuel line. I can understand why a replacement line would kink. I would suggest that you replace that particular line in such a way that you allow sufficient fuel line so that it can make a longer loop, thereby eliminating the kink. Be a little creative, making sure that there is no possibility of the longer line being chafed or cut in any way.  It is possible, very possible, that this is the cause of your hesitation or lag of performance as the fuel pressure could fall quickly when accelerating if that fuel pressure line was so restrictive.

I am getting ready to do this EXACT thin on the 16V car I just got. I have replaced these hoses on several of these types of cars many times. I usually find cutting it longer and letting it make a larger loop is a good way to keep it from kinking.

Thanks Hemi and Reaper AGAIN.

I did cut that one a little longer the second time, I might try something like this:

Not a bad idea. Be sure to use the fuel injection type clamps and I don't see why it wouldn't work.

 

The only negative I can say about it is that there are additional failure points, but honestly, as long as it it the correct hose and clamps and tightened down well...it shouldn't be an issue.

Replaced the bend this morning, I thought it came out nice and it makes me more comfortable because that bend is so close to the parking break cable.

It's a little after the fact but never to late, I replaced six short sections of fuel line two in the rear and four in the engine compartment, might there be any others I'm not seeing y tucked under the fuel rail? I hope not because it looks pretty tight around there.

Thanks

The only other place is back by the fuel pump. So, keep scooting backwards under the car. Just before the rear axle, in the center, you will see the fuel pump and fuel level sensors up on the fuel tank. There's 2 more sections there.

Thanks Reaper, 

I'll do some more scooting next weekend😉
