fuel pump fail, I think it's the pump... Options

[emerygt350]

So, was running fine, going to double check my timing, wouldn't restart (tried, but couldn't keep running). No pump sound and no pressure on the gauge (I love you, fuel pressure gauge). Whacked the pump with a screwdriver handle, nothing. Pushed it into the garage, figured I would give it one last listen in the quiet, heard a little bit of something, then a little grumble from the pump and I had pressure again. Started up just fine.

To me that says fuel pump, not relay. Any other experienced folk have some wisdom?

I need to move my pump up front anyway but I was planning on keeping the original.


now that I am thinking about it, it did struggle to start earlier in the day as well but cleared up.

Car sat for a couple months during the winter.

If you move the pump to the front, isn't it a best practice to also replace the tunnel fuel lines with stainless? The factory lines were not spec'd to be under 35psi, correct? I have my replacement 2 port fuel pump mounted on the engine firewall for this reason.

yes

i've left mine on the firewall for same reason.
but did replace the internal fuel lines with mild steel tubing.
discovered that original lines were not only brittle at exposed end but also for a good 6 or so inches back into the tunnel. the rest of the fuel lines were in remarkable condition.

what i have noticed is modern design turbine style two port does not like that location nearer engine as much as the old original pump.
suffer more in hot weather. i've rebuilt the original and a spare of the original to go back in.

think if i was committing to an inline long term i would go front end location.
+ steel pipes through cabin.
stainless makes me nervous. its brittle under stress.
thinking worst case scenario of a serious collision.
pray it never happens to me or anyone else in their 914.
but ss kits are a brilliant convenience.
i had to make my own anyway, differences due to rhd.
discovered its not that difficult to make your own lines if you have time and patience.
