Another no start issue

[brianlay]

In my experience seized pump will not blow the fuse. If you're getting a clunk when you apply power, that's all the testing you need.
Before you just throw another pump in there, I'd try to figure out why they're failing. Most likely debris in the tank.

I don't have any pics of that setup but i have been using a pre filter for many years even before the dansk fuel tank issues.I used them on cars that had been sitting and had fuel contamination issues.

Years ago i used a square plastic fuel filter for an audi, part # 811 201 511 D that worked fairly well, i have multiple crossover # for that filter but it has been
NLA for years. what i liked about this filter was it was semi clear and you could see what it was catching.

These days i use a napa 3299/ carquip 86299 and others and CUT THE HOSE BARB LIP OFF OF BOTH ENDS OF THE FILTER TO REDUCE THE LENGTH AS MUCH AS POSSIBLE . I butt the filter flush to the tank and the pump and connect with 2 short pieces of locally sourced 1/2 in fuel line and clamps.

The whole assy. just barely is able to be fit and takes a little fiddling with to work but will definitely save a new pump from damage due to debris in the tank whether its a new tank or old. When i say just barely i mean JUST BARELY, the pump and cap nut assy will hit/rub on the return line fitting of the tank but this is possible, i have done it many times and saved alot of pumps. This is not a permanent install and i usually would revert back to stock after a period of time, usually the next oil change or service.

I installed one of these filters in one of my 993's that was sitting in a used car lot for a couple years before i purchased it. There is alot more room in the 964/993 series fuel pump area and you can make a big loop with extended hoses and it works well.

You can use the long hose loop method on a G series car but it gets very crowded quickly and hard to keep the hose from kinking.

There has been previous discussion about the correlation between a new dansk tank and fuel pump failure if you do a search. At the price you stated i would say most likely it is a Dansk tank and i would not be suprised if thats what happened to your fuel pump. I have included a pic of a pump and filter so you get the general idea of what i have been doing, you want to keep the assy as short as possible.

hope this helps out RICHARD

That NAPA 3299 is also the go-to filter between the gas tank and electric fuel pump on mechanically injected Alfa's. Inexpensive insurance for your 911 (or Alfa) fuel pump. Just one of those p/n's forever stuck in my mind. John

one more note, if i remember correctly the micron count on these filters is something like 32 or something in that area, basically a ROCK stopper

Much appreciated Richard and jjeffries.

Called the installing shop (in OH and I’m in AR). They confirmed it’s a Dansk fuel tank, and they recognize the need for a filter between the tank and pump but the PO didn’t elect to have it put in. Thankfully, they are working with me see if they can help with a replacement.
