is the heath or ss diesel fuel pump worth its money because i noticed after marine injectors it seemed it was lacking fuel?

I don't have personal experience but most people get a Walbro LP. It is available through Lubricationspecialist.com (a sponsor).

the LP in my truck when i bought it was running minimum of 4.5psi at WOT and around 8+ at idle.
minimum allowable is around 2psi
i installed a heath HD LP. it is running about 4.5psi max at idle and just above 2psi at WOT.
i was told by them that thats acceptable.
ill be putting on my old LP.
i found a fuel pressure gauge isolator. i will install a mechanical fuel gauge in the cab to monitor.

Its better to just get the ACDelco for a 1993 truck, same plumbing more pressure, like 8-10psi idle.

The Walbro is a good choice, basically why get the Heath or SSDS LP when you can get something just as good and better for less. The Walbro unit will need some adapting of the lines and mounting it, not as plug and play as the unit from the 93s.

I have the Heath pump and get 6-7 psi at idle and 2-3 psi at WOT. I use an electric fuel pressure gauge. No isolator needed. I may try the 93 pump next time, as I would like a bit more pressure.

Heath claims it is specced higher than the 93 delco unit i believe.

I would go walbro, can get under 100 bux and puts out way more pressure and volume and outlasts these stocker joke pumps.

There is a vendor who sells the adapters for the Walbro pump, So you dont have to cut OEM lines.

I bought the SS Diesel pump about a year and a half ago. Never a problem. Next time I may just get one from O'Reileys for a 93. If ever I need one and if the price is right.

I was just doing a lot of stuff with plumbing copper lines and was wondering if I could just use the compression connectors on the steel fuel lines? Basically do steel line size (3/8"??) compression fitting to barb adaptor.

Then I could cut the steel lines if I wanted to remove rusty spot. Anyone try that before or know it wont work?

i was warned against using compression fittings like you say.
i removed my sender and fuel lines. i had them cut and had "bubble" fittings formed.
i beleive you can just clean it and slide rubber line over them and clamp it.
supply is 3/8" rubber and return is 5/16" rubber. slide it over several inches or six inches if you want. and use two clamps.- or three or four.
i found the best 3/8" line was a parker line - cant remember exactly, it was five digits - 37906 or something like that. i read it even stands up to B100. i have a parker marine diesel line, but it needs a barb, it will not stop leaking on the straight pipe, with bubble fitting, casing it too hard.

JAKE - if you come by here again - could you tell me, what electric gauge did you use?
